Unsymmetric dicopper(II) complexes of dinucleating ligands bearing chemically distinct co-ordination environments

Abstract

Dicopper(II) complexes of unsymmetrical dinucleating Schiff-base ligands bearing chemically distinct co-ordination sites have been prepared and their properties studied. The ligands were derived from the condensation of 4-bromo-2-formyl-6-(4-methylpiperazin-1-ylmethyl)phenol and 4-bromo-2-[(2-diethylaminoethyl)ethylaminomethyl]-6-formylphenol with 2-(aminomethyl)pyridine, 2-(2-aminoethyl)pyridine, and 2-(aminomethyl)-4-nitrophenol.
