| Two novel binuclear coordination complexes [Mn2 (C6H4O2Cl) 4 (H2O)(phen)2] (1) and {[Mn2 (btec)(bipy)2(H2O) 6] · H2O} (2) (H4btec =1,2,4,5-benzenetetracarboxylic) have been synthesized by hydrothermal method and characterized by single crystal X-Ray diffraction. In (1), two p-chlorobenzoate and one water molecule link two Mn(II) ions and form a binuclear complex. In (2), the two p-carboxylic groups of btec link two Mn(II) ions and form a binuclear structure. In (1) and (2),the Mn(II) ion is 6-coordinated. The surface photovoltage spectra of complex (1) and (2) indicate that both complexes show two positive SPV responses at 300-800nm. The SPV responses at lmax=348nm (1) and lmax=350nm (2) are assigned to the p→p* charge transfer transition, lmax=392nm (1) and lmax=445nm (2) are attributed to the charge transfer transition from ligand to metal (LMCT).
