A Novel Doubly Phenoxo-Bridged Cu(II) Trimer: Synthesis, Crystal Structure and Low-Temperature Magnetic Behaviour

Abstract

A novel doubly phenoxo-bridged Cu(II) trimeric complex, [trinuclear diperchlorato {2,2′-[1,3-propanediylbis (nitriloethylidyne)]bisphenolato}-tricopper] has been synthesised with a tetradentate Schiff base ligand and characterised by IR, electronic spectra, X-ray structure and variable temperature magnetic moments. The Cu1 centre has square pyramidal geometry where as the Cu2 centre achieves square planar geometry. The dihedral angle between the two planes, Cu1 – O1 – O2 and Cu2 – O1 – O2 is 26.50°.
