The colour isomerism and structure of copper co-ordination compounds. Part XVIII. The crystal structure of bis-(N-n-butylsalicylaldiminato)-copper(II)

Abstract

A three dimensional X-ray structural analysis of bis-(N-n-butylsalicylaldiminato)copper(II) has revealed a four-co-ordinate copper atom in the square planar configuration. The molecule as a whole is centrosymmetric and near planar, but is stepped so that the planes of the benzene rings are separated by 0·74 Å. The structure differs from that of related compounds in that there is no distortion towards a tetrahedral stereochemistry.
