Octahedral complexes of nickel(II) and copper(II) with triethylenetetra-amine

Abstract

The preparation and the physical properties of complexes of the type [Ni(trien)(en)]X₂(trien = triethylenetetra-amine; en = ethylenediamine; X = Cl, Br, I, SCN, NO₃, AcO, ClO₄, and BPh₄ and [Cu(trien)(en)]X₂(X = ClO₄ and BPh₄) are reported. The results indicate that both in solution and in the solid state the compounds are octahedral and that in solution the racemic mixture is present.
