Abstract: Four copper coordination complexes {[Cu(phen)(H2O)(o-tpha)]·H2O}n(1), [Cu2Cl4(phen)2](2), [Cu4Cl4(bipy)2](3) and [Cu2Cl2(phen)]n(4)(bipy=2,2'-bipyridyl, phen=1,10-phenanthroline, o-H2tpha=o-phthalic acid), were hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction. Complexes 1 and 4 both possess 1D infinite structure, complex 2 is a binuclear supramolecule connected by hydrogen bonds and complex 3 is a tetranuclear cluster. The surface photovoltage spectra(SPS) of four complexes all exhibit surface photovoltage responses(SPV) in the range 300—800 nm, however, the intensity, position and numbers of response bands are different obviously. The diffe-rences are mainly attributed to their different structures, valences and coordination environments of copper ions in the four complexes.
