Abstract A novel 1D chain cobalt complex， ［Co(4,4′-bipy)3(OH)2]n(1)， was synthesized by solvent evaporation method, using Co(NO3)2·6H2O， 1H-benzotriazole-1-acetic acid and 4,4′-bipyrine（4,4′-bipy） as materials. The structure was characterized by FT-IR, elemental analysis, X-ray single crystal diffraction. 1 belongs to monoclinic and space group C2/cwith a=18.057(4) , b=11.487(2) , c=24.590(5) , β=93.60(3)°, V=5 090.4(18) 3, Z=4, Dc=0.733 g·cm-3, μ=0.358 mm-1, F(000)=1 144, R1=0.093 0, ωR2=0.192 2. 1 was in distorted octahedral configuration with a central ion［Co(Ⅱ)］-coordinated with four N and two O. 2D(4,4)-connect (44·62) topological supramolecular network was constructied by intermolecular hydrogen bonding(O－H┈N) and π…π stack interactions formed by non-bridged 4,4′-bipys. The SPS results indicated that 1 exhibited photovoltaic conversion propertity with positive surface photovoltage responses in 300 nm~600 nm.
