Abstract

Abstract:

Three Cr（Ⅲ）coordination complexes [Cr(en)₂ox][Cr(en)(ox)₂]•2H₂O (1), [Co(NH₂NHCSNH₂)₃][Cr(ox)₃]•7H₂O(2), Cr(acac)₃(3) were synthesized by the groovy method(en=ethylenediamine, ox=oxalic acid, acac=acetylacetone) . The crystal structures of the complexes were determined by X-ray single crystal diffraction,and the complexes were characterized by UV-Vis and surface photovoltage spectrum(SPS). Surface photovoltage performance of the three complexes were emphatically studied, and compared with their UV-Vis spectra .The results of surface photovoltage spectra of complexes 1~3 indicate that the complexes exhibit better surface photovoltage responses in a range of 300~600 nm,and the determined surface photovoltage and UV-Vis spectra present comparatively well corresponding relation.

Key words: Cr(III) coordination complex, crystal structure, UV-Vis spectrum, surface photovoltage spectrum
