Abstract

Three novel oxamido-bridged heterobinuclear copper(II)-nickel(II) complexes derived from macrocylic oxamido compound with diamines and tetraazacyclam as blocking ligands were synthesized and characterized by IR, ESR and electronic spectra. Their formula is [Cu(L)Ni(en)₂](ClO₄)₂·0.5C ₂H₅OH·H₂O (1), [Cu(L)Ni(tmd)₂](ClO₄)₂·4H ₂O (2) and [Cu(L)Ni(rac-cth)](ClO₄)₂·CH₃OH (3), where L=1,4,8,11-tetraazacyclotradecanne-2,3-dione, en=1,2-diaminoethande, tmd=1,3-diaminopropane and rac-cth is rac-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane. The crystal structures of the three complexes have been determined. The structures consist of binuclear units in which the copper(II) ion is in a square-planar environment and linked to the nickel(II) ion via the exo-cis oxygen atoms of the oxamido macrocyclic ligand, with Cu···Ni separations of 5.311 (1), 5.420 (2) and 5.307 Å (3), respectively. The temperature dependence of the magnetic susceptibility for 1, 2 and 3 was analyzed by means of the Hamiltonian Ĥ=-2JŜ_NiŜ_Cu, leading to J=-52.8, -45.7 and -56.9 cm^-1 for 1, 2 and 3, respectively.
