Copper(II) Complexes with Some Hexaaza Macrocyclic Ligands

The template condensation of the chlorocarbons carbon tetrachloride, 1, 1, 2, 2-tctrachloroethylene or 1, 1, 2, 2- tetrachlo-roethane with diethylenetriamine in the presence of copper(II) hydroxide in butanol yields dimetallic copper(II) complexes of the macrocyclic ligands 1, 4, 7, 9, 12, 15-hexaaza-8, 8, 16, 16-tetrachlorocyclohexadecane (HTCH), 1, 4, 7, 10, 13, 16-hexaaza-8, 9, 17, 8-tetrachlorocyclooctadeca-8, 17-diene (HTOD) or l, 4, 7, 10, 13, 16-hexaaza-8, 9, 17, 18-tetrachlorocyclooctadccane (HTCO). respectively. The metal-free ligand hydrochlorides have also been obtained by removing the metal as CuS from the acidic solutions of the corresponding complexes. The formulation of the macrocyclic complexes as [Cu 2 (HTCH)(H 2 O) 2 ]Cl 4 .8H 2 O, [Cu 2 (HTOD)(H 2 O) 2 ]Cl 4 .H 2 O and [Cu 2 (HTCO)(H 2 O) 2 ]Cl 4 . and the ligands as C 10 H 22 N 6 Cl 4 . 6HCl (HTCH·6HC1), Cl 2 H 22 N 6 Cl 4 ·6HCl (HTOD·6HCl) and C 12 H 26 N 6 Cl 4 ·6HCl (HTCO.6HCl) is supported by the elemental analyses, conductivity measurements, molecular weights by mass spectroscopy and infrared spectra.
