Synthesis, Characterization, and Crystal Structures of Copper(II) and Zinc(II) Complexes Derived From the Tridentate Schiff Bases 2-[1-(pyridin-2-ylmethylimino) ethyl]phenol and (1-pyridin-2-ylethylidene)pyridin-2- ylmethylamine

Abstract

A centrosymmetric phenolate oxygen bridged dinuclear copper(II) complex [Cu2(L1)2(N3)2] (1) and a mononuclear zinc(II) complex [Zn(L2)(NCS)2] (2), where HL1 = 2-[1-(pyridin-2-ylmethylimino)ethyl]phenol and L2 = (1-pyridin-2-ylethylidene)pyridin-2-ylmethylamine, were synthesized and structurally characterized by physicochemical methods and single-crystal X-ray diffraction. The Cu atom in (1) is five-coordinated in a slightly distorted square pyramidal geometry, and the Zn atom in (2) is five-coordinated in a severely distorted square pyramidal geometry.
