Abstract

A series of copper(II) complexes with ligands derived from the Schiff base reaction of pyridine- 2-carboxaldehyde or 6-methylpyridine-2-carboxal- dehyde with aniline, benzylamine or 2-phenylethylamine has been prepared. These complexes have been characterized by spectroscopic methods. The electronic spectrum of bis(N-phenyl-(6-methyl-2- pyridyl)methylimine) copper(II) tetrafluoroborate has an absorption band at a much higher energy and molar absorptivity than the other complexes. The appearance of this band indicates a major change in geometry caused by the combined steric demands of the 6-methyl group on the pyridine aromatic ring and the rigid aromatic ring of the phenyl group on the imine nitrogen atom.
