Abstract
A new family of binuclear Cu(II)–Cu(II) complexes with a hexadentate Schiff base ligand containing imine-phenol end groups has been studied as an EPR spectral model of the binuclear CuA centre of nitrous oxide reductase. The complexes have been characterised by elemental analysis, solution electrical conductivities, IR, UV-vis, EPR spectral, magnetic studies and geometrical optimisation by molecular mechanics (MM2) method.
