Abstract
The title compound crystallises in the monoclinic system, a= 10·40. b= 5·88, c= 15·61 Å, β= 95·2°, with space group P21/c. The structure was solved from visually estimated photographic X-ray data by the heavy-atom method and refined by least-squares techniques to R0·097 for 1024 reflections. It differs from polyrmorphs already studied in being strictly square-planar in co-ordination stereochemistry. It also shows a much higher degree of molecular planarity than expected. Intermolecular interactions of any significance are lacking so that the geometry of the complex can be discussed in terms of internal factors. The observations are interpreted in terms of a relationship between molecular conformation and metal–ligand bonding.Keywords
