Abstract

Six macrocyclic complexes, were synthesized by reaction of 1,4-bis(2-carboxyaldehyde phenoxy)butane and various amines and their copper(II) perchlorate complexes were synthesized by template effect reaction of 1,4-bis(2-carboxyaldehyde phenoxy)butane, Cu(ClO4)2 center dot 6H(2)O and amines. The metal-to-ligand ratios were found to be 1 : 1. Cu(II) metal complexes are 1: 2 electrolytes as shown by their molar conductivities (Lambda(M)) in DM F (dimethyl formamide) at 10(-3) M. The Cu(II) complexes are proposed to be square planar based on elemental analysis, FT-IR, UV-Vis, magnetic susceptibility measurements, molar conductivity measurements, and mass spectra.
