Resumo |
The unsymmetrical1y substituted diorganotellurium dihalides [2-(4,4'-N0<sub>2</sub>C<sub>6</sub>H<sub>4</sub>CHNC<sub>6</sub>H<sub>3</sub>Me]RTeX<sub>2</sub> (R = 4-MeOC<sub>6</sub>H<sub>4</sub>, X = Cl,<br /><b>1a</b>; Br, <b>1b</b>; I, <b>1c</b>; R =4-MeC<sub>6</sub>H<sub>4</sub> ; X = Cl, <b>2</b>; R =C<sub>6</sub>H<sub>5</sub>, X = Cl, 3) were prepared in good yields and characterized by solution and solid-state <sup>125</sup>Te NMR spectroscopy, IR spectroscopy and X-ray crystallography. In the solid-state, molecular structures of <b>1a</b> and <b>1c</b> possess scarcely observed 1,4-type intramolecular Te···N secondary interaction. Crystal packing of these compounds show an unusually rich diversity of intermolecular secondary, Te·· ·0, Te· .. \ and 1···1 interactions, Te·· ·π contacts as well as extensive<br />π-stacking of the organic substituents.<br /> |
