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‐ (LCN) groups as chelating ligands were prepared by reactions of lithium compound LCNLi with an appropriate amount of (organo)tin halide. The geometry of tin in 1 ((LCN)2SnPhCl) is on the boundary between octahed...

Description
Summary:Tri‐ and di‐organotin(IV) compounds containing one or two 2‐(dimethylaminomethyl)phenyl‐ (LCN) groups as chelating ligands were prepared by reactions of lithium compound LCNLi with an appropriate amount of (organo)tin halide. The geometry of tin in 1 ((LCN)2SnPhCl) is on the boundary between octahedral and trigonal bipyramidal. The diorganotin compounds 2–4 ((LCN)2SnX2, 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 (LCNSnPhCl2) has a trigonal bipyramidal structure with non‐equivalent chlorine atoms. Copyright © 2005 John Wiley & Sons, Ltd. Tri‐ and di‐organotin(IV) compounds containing one or two 2‐(dimethylaminomethyl)phenyl‐ (LCN) groups as chelating ligand(s) were studied by diffraction methods and NMR techniques.
