cze Structure and properties of double-C,N-chelated tri-and diorganotin(IV) halides Tri- and di-organotin(IV) compounds containing one or two 2-(dimethylaminomethyl)phenyl-(L-CN) groups as chelating ligands were prepared by reactions of lithium compound (LLi)-Li-CN with an appropriate amount of (organo)tin halide. The geometry of tin in 1 ((L-CN)(2)SnPhCl) is on the boundary between octahedral and trigonal bipyramidal. The diorganotin compounds 2-4 ((L-CN)(2)SnX2, where X = Cl, Br, I) have a distorted octahedral geometry in the solid state and show dynamic processes in solution with a lowering of activation energy of the dynamic process going from diiodide to dichloride derivative. Compound 5 ((LSnPhCl2)-Sn-CN) has a trigonal bipyramidal structure with non-equivalent chlorine atoms. Copyright (c) 2005 John Wiley & Sons, Ltd.
