Trinuclear copper(II) complexes of some aza macrocycles

Abstract

dotriacontane (DTTD) derived from triethylenetetramine, 1,2-diaminoethane and chlorocarbons (carbon tetrachloride, 1,l,2,2-tetrachloroethane and hexachloroethane, respectively) have been studied. Complexes [Cu 3 (DDST)]Cl 6 , [Cu 3 (DOCD)]Cl 6 and [Cu 3 (DTTD)]Cl 6 Á H 2 O and the copper ion-free ligand hydrochlorides DDST Á 12HCl and DOCD Á 12HCl are supported by elemental analyses, conductivity measurements and spectroscopic studies. Potentiometric equilibrium studies on DDST and DOCD hydrochlorides and their copper complexes also support the structures.
