Synthesis and Characterization of Copper(II) Complexes with Salen-Type Bisoxime Chelating Ligand

摘要

Two Cu(II) complexes 1 and 2 have been synthesized by the reaction of eopper(II) picrate tetrahydrate and copper(II) perchlorate hexahydrate with a Salen-type bisoxime chelating ligand (H2L = 6,6'-dimethoxy-2,2'-ethylenedioxybis(nitrilomethylidyne)diphenol) and characterized by elemental analyses. IR spectra, UV-visible spectra, TG-DTA analyses and molar conductances. The Salen-type bisoxime is a good tetradentate N2O2-donating ligand and the likely formula of the Cu(II) complexes may be suggested as CuL·(HPic)2 (1) and CuL·2H20 (2).
