Synthesis, structure, thermal stability and surface photo-electric property of a novel three-dimensional Co(II) complex

A novel cobalt(II) complex [Co3(oba)3(phen)2]n(H2oba = 4,4′-oxybis benzoic acid, phen = 1,10-phenanthroline) has been synthesized by hydrothermal method and characterized by single crystal X-ray diffraction, IR, UV–vis, thermal stability and Surface Photovoltage Spectroscopy (SPS). Structural analysis indicated that the complex is a 3D structure with the trinuclear building unit of [Co3(oba)3(phen)2] bridged by the oba ligands. The SPS of complex indicates that there are positive response bands in the range of 300–600 nm showing photo-electric conversion properties. There are good relationships between SPS and UV–vis spectra.
