Three NAPH (1,8-naphthalate dianion) bridged dicopper(II) complexes have been synthesized, namely [NAPHCu2(_-X)2_2H2O]_nH2O, X = OH- (1), OAc- (2) and Cl- (3). NAPH was found to have the ability to form a dinuclear core with _-X as additional ligand. Based on IR, elemental analysis and electronic spectra, these complexes were found to have heterocyclic structure with both NAPH and _-X as bridging ligands. The temperature dependence of magnetic susceptibilities of 1 has been studied, giving the exchange integral of J = -216 cm-1, g = 2.09. This result is in agreement with proposed dihydroxo-bridged structure of 1, since Cu2O2 unit normally undergoes a strong antiferromagnetic interaction. Significantly, these complexes were found to exhibit catalase- like activity.
