Abstract

Two heterometallic complexes [{CuII (HLOX) NiII (N3)} 2] and [(tmtacn) CoIII (μ-OH) CuII (LOX) NiII (OH2) 2][ClO4] 2 (tmtacn= 1, 4, 7-trimethyl-1, 4, 7-triazacyclononane) containing the same [CuIINiII] core embedded in an unsymmetrical dicompartmental imine-oxime ligand H4LOX have been synthesized and characterized. Their crystal structures show that the CuII resides at the N (oxime) 2O (phenolate) 2 site and assumes a planar geometry. ...
