Abstract
A three-dimensional X-ray structural analysis of the orthorhombic form of bis-(N-ethylsalicylaldiminato)copper(II) has revealed an asymmetric unit containing two independent molecules which differ slightly in molecular geometry. The copper atoms are quadricovalent with their co-ordination ‘squares’ slightly distorted towards tetrahedral configurations, the angles between chelate rings being 7·4° in one molecule and 11·4° in the other. The copper–oxygen and copper–nitrogen bond lengths lie between 1·860, and 1·887, and 1·987 and 2·005 Å respectively.Keywords
