Two coordination polymers called [Ni(L)_2]_n(1) and [Ni(2,2?-bpy)_22(H_2O)]n (2)(HL = 4-benzoimidazol-1-yl-methyl benzoic acid, 2,2?-bpy = 2,2?-dipyridine) were synthesized by solvothermal reaction simultaneously and characterized by elemental analyses, thermogravimetric analysis, X-ray powder diffraction, IR spectroscopy and single-crystal X-ray diffraction analysis. Complex 1 crystallizes in monoclinic system, space group P2_1/c with a = 14.673(3), b = 10.773(2), c = 16.566(3) ?, V = 2559.2(8) ?~3, Z = 4 and F(000) = 1160. 2 also crystallizes in monoclinic system, space group C2/c with a = 15.404(3), b = 12.652(3), c = 6.5362(13) ?, V = 1246.2(5) ?~3, Z = 4 and F(000) = 712. The bridging L ligand connects the Ni~Ⅱ cations into a 2D network in complex 1, while 2 shows a 1D structure formed through the two O atoms of SO_4~(2-) ions connecting the molecule. The catalytic properties indicate that complex 1 shows good catalytic activities for the cyanosilylation of 4-chlorobenzaldehyde. In addition, fluorescence property of complex 1 which quenches the excitation intensity in solid state was investigated at room temperature.
