ELECTRONICALLY INDUCED MOLECULAR DISTORTIONS THE CRYSTAL STRUCTURE OF BIS(TERPYRIDINE)COPPER(II) NITRATE

Abstract

Although a large number of mono- and bis-terpy¹ complexes have been prepared,² only a few structural studies of the mono-terpy complexes have been reorted. Our study of bis(terpy)copper(II) nitrate the first crystal structure determination of bis(terpy) complex and reveals an unusual and unexpected angular distortion of the terpy ligand. This distortion results from the d9 consguration the Cuoion and from the fact that all six nitrogen atoms of the terpy ligand are coordinated to copper atom.
