Abstract
Heterotrinuclear complexes of the type [Cu2(TETA)2Cl4M] (M = Si, Ge, S n, Ti and Zr; TETA = triethylene tetramine) have been prepared by dire ct reaction of [Cu[TETA)]Cl2 with MCl4 in a 2:1 ratio in MeOH. The com pounds have been characterized by elemental analyses, e.s.r., electron ic and i.r. spectra, magnetic susceptibility and conductivity measurem ents. The results indicate that [Cu(TETA)]Cl2 is square planar and ion ic, while its heterotrinuclear complexes, [Cu2(TETA)2Cl4M], are covale nt with an octahedral environment around the copper(II) ion.
