| Abstract: | Summary Heterotrinuclear complexes of the type [Cu2(TETA)2Cl4M] (M = Si, Ge, Sn, Ti and Zr; TETA = triethylene tetramine) have been prepared by direct reaction of [Cu[TETA)]Cl2 with MCl4 in a 2 1 ratio in MeOH. The compounds have been characterized by elemental analyses, e.s.r., electronic and i.r. spectra, magnetic susceptibility and conductivity measurements. The results indicate that [Cu(TETA)]Cl2 is square planar and ionic, while its heterotrinuclear complexes, [Cu2(TETA)2Cl4M], are covalent with an octahedral environment around the copper(II) ion. |
