The synthesis and characterization of a binuclear copper(II) complex of a Schiff base derived from salicylaldehyde and (1S,2S)-(+)_D-1-phenyl-2-amino-1,3-propanediol are described. A distorted square-planar configuration about the copper centers is proposed on the basis of its spectral properties and its reduced magnetic moment in solution. The complex reacts in solution with a series of ligands to form bis(ligand) adducts in which the dimeric unit remains intact. The bis(imidazole) adduct exhibits catalase activity, and in the presence of hydrogen peroxide a band near 440 nm is observed that is most probably a O₂^2--Cu(II) charge-transfer transition.
