Abstract

A new tetradentate bis-oxime chelating ligand, 5,5'-dihydroxy-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H4L) and its two Cu(II) complexes 1 and 2 have been synthesized by the reaction of H4L with copper(II) acetate monohydrate and copper(II) picrate tetrahydrate, respectively. The complexes have been characterized by elemental analyses, IR spectra, UV-visible spectra, TG-DTA and molar conductances. The salen-type bisoxime chelating ligand is a good tetradentate N2O2-donating ligand and the likely formulae of the Cu(II) complexes may be suggested as [Cu(H2L)]·CH3CH2OH·2H2O (1) and [Cu2(H2L)(picrate)2]·H2O (2).
