SYNTHESIS AND CRYSTAL-STRUCTURE OF [LI(THF)4][((T)BUCP)YB(NPH2)3]

The title complex [Li(THF)4] [(tBuCp)Yb(NPh2)3] was synthesized by the reaction of t-butylcyclopentadienyl ytterbium dichloride with 2 equivalents of LiNPh2 in THF, hexane, and toluene at -78-degrees-C. The complex was characterized by elemental analysis,

SYNTHESIS AND CRYSTAL-STRUCTURE OF [ME4C2CP2SMCL-CENTER-DOT-THF]2

Me4C2(C5H4MgCl)2(THF) (THF = tetrahydrofuran) reacts with anhydrous SmCl3 in THF to give [Me4C2CP2SMCl.THF]2. The molecule is a dimer. Sm1 and Sm2 are bridged unsymmetrically by two chlorine atoms [Sm(1)-CI(1) 2.787(2), Sm(1)-Cl(2) 2.848(2), Sm(2)-Cl(1) 2

SYNTHESIS AND X-RAY CRYSTAL-STRUCTURE CHARACTERIZATION OF ZN2(HPO4)(3).H3NCH2CH2NH3

A novel framework material, Zn-2(HPO4)(3).H3NCH2CH2NH3, has been synthesised and its crystal structure determined by single crystal X-ray diffraction.

SYNTHESIS AND CRYSTALLIZATION BEHAVIOR OF (PP-MA)-G-PEO

A new graft copolymer (PP-MA)-g-PEO was synthesized by means of the chemical reaction between maleated polypropylene (PP-MA) and mono hydroxyl poly(ethylene oxide) (PEO-OH). The effect of reaction conditions on the degree of grafting of PEO-OH was studied
