Patriotismus: Sozialpsychologische Aspekte

In public discourse the term patriotism is used with either positive or negative connotations. What does social-psychological research have to say about the consequences of patriotism? Patriotism can be defined analogous to the concept of social identity (Tajfel I Turner, 1979). Thus, results from social identity research are relevant. According to this research, people have a desire for positive social (national) identity. This desire can lead to discrimination of outgroups, but does not do so in every case. Differentiations of the concept of patriotism show that there are qualitatively different forms of patriotism that are in specific ways linked to partly contradictory variables. For example, constructive patriotism is associated with commitment against xenophobia while blind patriotism as an opposing form is associated with xenophobia. It is argued with reference to self-categorization theory (Turner et al., 1987) that patriotism as such is neither good nor bad. Rather, its consequences depend on the values and norms by which national identity is subjectively defined.

Ist patriotischer Nationalstolz wünschenswert? Eine differenzierte Analyse seiner psychologischen Bedeutung

Previous studies found that patriotic national pride (e.g., pride in democracy) - as opposed to nationalistic national pride (e.g., pride in being German) - has an attenuating effect on ethnocentrism, which is desirable from a democratic standpoint. Here it is hypothesized (1) that patriotic pride can be ascribed to the three components national identification, importance of democratic aspects of Germany, and belief in existence of democratic aspects of Germany, and (2) that these components exert in part conflicting effects on ethnocentrism and other variables. In two questionnaire studies (N-1 = 121, N-2 = 150) it is shown that (1) the three components do predict patriotic national pride and (2) the democratically desirable effects of patriotic pride trace back primarily to the importance of democratic aspects. In conclusion, from a democratic standpoint, it is positive valuation of democratic aspects and not patriotic pride that should be nurtured.

Zur kognitiven Konstruktion von (Un-)Gerechtigkeit militärischer Gewalt: Die moralische Beurteilung des Kosovo-Kriegs

With reference to the Kosovo war, we examined how the (un-)justness of military intervention is cognitively constructed. Four types of reinterpretation were hypothesized to relate to positive evaluation of the intervention: minimisation of negative consequences of NATO's intervention, denial of responsibility of the Western countries for the war, blame of Yugoslavia, and justification of the intervention through positive motives. As determinants of evaluation of the war, belief in a just world, militarism-pacifism, authoritarianism, and diffuse political support were taken into account. Hypotheses were tested with 165 university students using structural equation modelling. Consistent with our assumptions, the four types of reinterpretation related strongly to positive evaluation of the intervention, showing their relevance with regard to military intervention. Further, the assessed political attitudes influenced evaluation of the war while, contrary to predictions, belief in a just world did not. The causal status of the reinterpretations and the interplay of belief in a just world and political attitudes are discussed.

3,5-dimethyl-4-amino-1,2,4-triazole (Dat) as a tridentate ligand in the polymeric cations of [Ag-3(Dat)(2)](NO3)(3)

Colourless single crystals of [Ag-3(Dat)(2)](NO3)(3) were obtained from a reaction of silver(l) nitrate and 3,5-dimethyl-4-amino-1,2,4-triazole (Dat). In the crystal structure (orthorhombic, Fdd2, Z = 8, a = 1100.1(2), b = 3500.3(2), c = 1015.4(3) pm, R, = 0.0434) there are two crystallographically non-equivalent silver sites in a one (Ag1) to two ratio (Ag2). Both resemble linear N-Ag-N coordination although angles are 163 degrees and 144 degrees, respectively Each Dat ligand coordinates with the two ring nitrogen atoms at 216 to 219 pm and with one amino-nitrogen atom at 229 pro. According to the composition [Ag-3(Dat)(2)](3+) = [(Dat)Ag-3/2](3+), a polymeric structure is built with all Ag+ ions bridging.

The persistence of the HgCl2 molecule in five new compounds in the system (NH4)(w)HgxCly(H2O)(z) with w : x : y : z=1 : 5 : 11 : 0, 2 : 3 : 8 : 1, 4 : 3 : 10 : 2, 2 : 1 : 4 : 1, and 10 : 3 : 16 : 0

Five new compounds in the system (NH4)Cl/HgCl2/H2O have been obtained as colourless single crystals, (NH4)Hg5Cl11, (NH4)(2)Hg3Cl8(H2O), (NH4)(4)Hg3Cl10(H2O)(2), (NH4)(2)HgCl4(H2O), and (NH4)(10)Hg3Cl16. In all of these, as in HgCl2 itself, (almost) linear HgCl2 molecules persist with Hg-Cl distances varying from 229 to 236 pm. In (NH4)(10)Hg3Cl16 there are also tetrahedra [HgCl4] with d(Hg-Cl) = 247 pm present. If larger Hg-Cl distances (of up to 340 pm) are considered as belonging to the coordination sphere of Hg-II, the structures may be described as consisting of isolated octahedra and tetrahedra as in (NH4)(10)Hg3Cl16, edge-connected chains as in (NH4)(2)HgCl4(H2O), edge-connected chains and layers of octahedra as in (NH4)(4)Hg3Cl10(H2O)(2), corrugated layers of edge-connected octahedra as in (NH4)(2)Hg3Cl8(H2O), and, finally, a three-dimensional network of connected six- and seven-coordinate Hg-Cl polyhedra as in (NH4)Hg5Cl11. The water molecules are never attached to Hg-II. The (NH4)(+) cations, and sometimes Cl- anions, play a role for electroneutrality only.

Tetrahedra and vertex-sharing double tetrahedra in the ammonium iodomercurates(II) (NH4)(7)[HgI4](2)[Hg2I7](H2O) and (NH4)(3)[Hg2I7]

The new ammonium iodomercurates(II), (NH4)(7)[HgI4](2)[Hg2I7](H2O) (1) and (NH4)(3)[Hg2I7] (2) contain isolated tetrahedra and vertex-sharing double tetrahedra as the anions. The crystal structures were determined from single-crystal X-ray diffraction data: 1: orthorhombic, Pnma (no. 62), a = 2175.9(2), b = 1781.8(2), c = 1256.2(2) pm, Z = 4. R-1 [I-0 > 2 sigma(I-0)] = 0.0520; 2: monoclinic, P2(1)/c (no. 14), a = 1259.0(2), b = 773.2(1), c = 2172.4(3) pm, beta = 101.18(2)degrees, Z = 4, R, [I-0 > 2 sigma(I-0)] = 0.0308.

The crystal structures of two ammonium bromomercurates(II), (NH4)Hg5Br11 (1) and (NH4)(4)HgBr6 (2), were determined from single-crystal X-ray diffraction data: 1: monoclinic, C2/m (no. 12), a = 1231.3(3), b = 1517.4(3), c = 680.4(2) pm, beta = 118.78(2)degrees, Z = 2, R-1 = 0.0391 for I-0 > 2 sigma(I-0); 2: tetragonal, P4/mnc (no. 128), a = 925.6(1), c = 887.2(1) pm, Z = 2, R-1 = 0.0370 for I(0 >)2a(I-0). According to (NH4)Br[HgBr2](5) and (NH4)(4)Br-4[HgBr2] they both contain [Br-Hg-Br] molecules. Additional bromide ions are only loosely attached to the mercury atoms, however involved in (NH4)(+)-Br- bonding.

Bis(trifluoromethyl)mercury(II) complexes with purine and 3,5-dimethyl-4 '-amino-triazole as ligands, [Hg(CF3)(2)(Pur)](4) and [Hg(CF3)(2)(Dat)](2)

Colourless single crystals of [Hg(CF3)(2)(Pur)](4) and [Hg(CF3)(2)(Dat)](2) were obtained from aqueous and etheric solutions of the respective components Purine, (imidazo[4,5-d]pyrimidine, Pur), 3,5-dimethyl-4 '-amino-triazole (Dat) and bis(trifluoromethyl)mercury(II), Hg(CF3)(2). [Hg(CF3)(2)(Pur)](4) crystallizes with the tetragonal system (P-4, Z = 8, a = 1486.8(2), c = 1026.2(l) pm, R-all = 0.0657) with tetrameric molecules consisting of four purine molecules bridged by slightly bent Hg(CF3)2 molecules forming a cage with the CF3 ligands surrounding this cage. The two modifications of [Hg(Dat)(CF3)2]2 (1: 170 K, triclinic, P-1, Z = 2, a 814.9(2), b = 845.4(2), c = 968.4(3) pm, alpha = 106.55(2)degrees, beta= 103.41(2)degrees, gamma = 110.79(2)degrees, R-all = 0.1189; II: monoclinic, P2(1)/c, Z = 8, a = 879.8(2), b = 1731.0(3), c = 1593.9(3) pm, beta = 106.89(2)degrees, R-all = 0.1199) both contain dimeric molecules that are stacked parallel to one crystal axis to strands which are arranged in a parallel fashion in I and rotated against each other in 11 by 110 degrees. In both, the tetrameric [Hg(CF3)(2)(Pur)](4) and the dimeric [Hg(CF3)(2)(Dat)](2) the Hg(CF3)(2) molecules are slightly bent (around 167 and 170 degrees) and rather weakly attached to the N-donor ligands Pur and Dat with Hg-N distances around 272 pm, although in both cases the Hg atoms bridge between two ligand molecules.

Mercurous azide, Hg-2(N-3)(2)

White polycrystalline mercurous azide, Hg-2(N-3)(2), is obtained by combining aqueous solutions of NaN3 and Hg-2(NO3)(2).2H(2)O (made viscuous by addition of tetramethoxysilane and heating at 65 degreesC). The crystal structure was solved and refined from X-ray powder diffraction data (monoclinic, P2(1)/n, a = 596.07(2) pm, b = 1259.07(4) pm, c = 357.95(1) pm, beta 103.253(2)degrees, Z = 2, R-B = 0.0519). Solid Hg-2(N-3)(2) contains, essentially, molecules of that composition with Hg-Hg distances of 254.4(3) pm, Hg-N distances of 218(2) pm and Hg-Hg-N angles of 178.7(6)degrees. Weak intermolecular interactions with Hg-N distances starting at 280(3) pm lead to a three-dimensional structure.

Affinity of divalent mercury towards nitrogen donor ligands

As with gold, relativistic effects are important in the chemistry of mercury Together with the closed-shell d(10) configuration of Hg2+ they account for the special bonding schemes as preferred linear coordination with highly covalent contributions to chemical bonding or special affinities to nitrogen and sulfur that are so prominent in mercuric chemistry This research report summarizes recent research on coordination compounds with halogen, oxygen and, especially, nitrogen as direct bonding partners of di-valent mercury and their competition with each other. In a rather systematic way N-donor ligands with one, two and more than two nitrogen atoms have been inspected in order to elucidate the influences that lead to the special bonding schemes of Hg-II-N compounds.

Pyrimidine and pyrazine as N-donor ligands in mercurous complexes: [Hg-2(Pym)]NO3)(2), [Hg-2(Pym)](ClO4)(2), and [Hg-2(Pyp)(2)](ClO4)(2)

Colourless single crystals of [Hg-2(Pym)](NO3)(2), [Hg-2(Pym)](ClO4)(2) and [Hg-2(Pyp)(2)](ClO4)(2) were obtained from aqueous solutions of the respective components Hg-2(NO3)(2).2H(2)O, Hg-2(ClO4)(2).6H(2)O, pyrimidine (Pym) and pyrazine (Pyp). The crystal structures were determined from single-crystal X-ray diffractometer data. [Hg-2(Pym)](NO3)(2): monoclinic, C2/c, Z = 8, a = 1607.4(2), b = 652.79(7), c = 2000.5(2) pm, beta = 103.42(2)degrees, R-all = 0.0530; [Hg-2(Pym)](ClO4)(2): orthorhombic, Pnma, Z = 4, a = 1182.7(2), b = 1662.5(2), c = 607.9(1) pm, R-all = 0.0438; [Hg-2(Pyp)(2)](ClO4)(2): orthorhombic, Aba2, Z = 4, a = 1529.39(9), b = 1047.10(14), c = 1133.49(15) pm, R-all = 0.0381. The crystal structures of [Hg-2(Pym)](NO3)(2) and [Hg-2(Pym)](ClO4)(2) contain polymeric cationic chains [Hg-2(Pym)](+) that are arranged to corrugated layers between which the anions are situated. [Hg-2(Pyp)(2)](ClO4)(2) consists of polymeric cationic layers that are built from (Hg-2)(2)(Hg-2)(2/2)(Pyp)(4) rings connected to each other; the perchlorate tetrahedra are located between these layers.
