Synthesis, crystal structure and photoelectric property of two novel coordinated complexes constructed by 4,4′-bipyridine and sebacic acid

Two two-dimensional (2D) new complexes: [M(bpy)(C10H16O4)H2O] [M = Ni (1), Co (2); bpy = 4,4-bipyridine, C10H18O4 = sebacic acid] were synthesized by the hydrothermal reaction at 180 °C and characterized by elemental analysis, infrared spectra, and thermogravimetric spectra, single-crystal X-ray diffraction and surface photovoltage spectrum (SPS). The single-crystal X-ray diffraction showed that both complexes are isomorphous, crystallized in monoclinic system, and space group P21/c. In addition, The results of SPS for complexes (1) and (2) indicate that these two complexes exhibit positive surface photovoltage response in the range of 300–800 nm, which can be assigned to LMCT and d → d∗ electronic transition. The SPS spectra of the two complexes are consistent with their UV–Vis spectra.
