Complexes of some 3d metal ions of the Schiff's base, N,N′-di-4- (4′-pentyloxybenzoate) salicylidene-1″, 3″-diamino-2″- propanol: Synthesis and spectral studies

Abstract

A nematogenic Schiff's base, N,N′-di-4-(4′-pentyloxybenzoate) salicylidene-l″, 3″-diamino-2″-propanol, (abbreviated as H2L6), was synthesized and its structure studied by elemental analyses, mass, NMR and IR spectra. The Schiff's base behaves as a dinegative hexa/tetradentate species in its metal complexes of the general formula, [ML6]n where MII, Co, Ni, Cu and Zn. Their structural characterizations were made by various spectroscopic techniques. © 2011 Elsevier B.V. All rights reserved.
