A coordination polymer [Ni(pbc)2(H2O)]n(Hpbc = 3-pyrid-4-ylbenzoic acid) has been prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction,IR and elemental analysis.The crystal is of monoclinic,space group C2/c with a=19.624(5),b=12.029(5),c=19.452(5),β=104.45(5)°,C24H18NiN2O5,Mr=473.11,V=4447(2)3,Dc=1.413 g/cm3,F(000)=1952,μ = 0.91 cm-1,Z = 8,the final R=0.0424 and wR=0.0871 for 3757 reflections with I>2σ(I).X-ray diffraction analysis reveals that the pbc-ligands act as diconnectors to link two Ni(Ⅱ) centers and adopt two coordination modes of μ2-N,O and μ2-N,O,O to form infinite wavy nickel-carboxylate chains along the bc plane.The topological analysis of compound [Ni(pbc)2(H2O)]n reveals that it is a typical CdS framework.
