One new coordination polymer, [Ni(m-bix)(m-BDC)](1, m-bix = 1,3-bis(imidazol-1-ylmethyl)benzene, m-BDC = 1,3-benzenedicarboxylic acids), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, TGA and X-ray single-crystal diffraction. The green block crystal of complex 1(C22H18N4Ni O4) belongs to monoclinic system, space group P21/c with a = 10.0418(3), b = 23.8651(6), c = 8.7872(2) A, β = 112.333(3)o, V = 1947.88(9)A3, Z = 4, Dc = 1.572 g/cm3, Mr = 461.11, F(000) = 952, R = 0.0335 and w R = 0.0683 for 2827 observed reflections(I > 2σ(I)). Complex 1 exhibits a novel 6-connected 3D sxd type topological framework. The magnetic characterization of complex 1 shows antiferromagnetic coupling exchange.
