Preparation and crystal structures of two forms of trans-[CuCl2{N(H)SPh2}2 ]; an unusual example of square planar/pseudo-tetrahedral isomerism in a neutral copper(II) complex
Abstract
At ambient temperatures, in acetonitrile,
S,S-diphenylsulfimide reacted with CuCl
2
(molar ratio 2∶1) to give
trans-[CuCl

{N(H)SPh

]; depending upon the crystallisation technique this can be
isolated as either blue (perfect square-planar geometry) or green
(pseudo-tetrahedral) crystals which do not interconvert in the solid
state.
