Utilizing mononuclear complex Ni(2-mpac)2(H2O)2 as the molecular building block,a novel coordination polymer [Ni2(2-mpac)4(4,4'-bpy)·2H2O]n (1,2-mpac = 5-methyl-2-pyrazinecarboxylic acid, 4,4'-bpy = 4,4'-bipyridine) was successfully synthesized and structurally characterized by X-ray single-crystal diffraction method. Crystal data: monoclinic, space group C2/c, a = 23.870(1),b = 9.887(4), c = 18.929(9) (A),β= 126.840(5)°, V = 3575(3) (A)3, Z = 4, S = 1.046, μ = 1.594 mm-1,F(000) = 1768 and Dc = 1.127 g·cm-3. The final R = 0.0351 and wR = 0.0792 for 2372 observed reflections with Ⅰ＞ 2σ(Ⅰ) and R = 0.0564 and wR = 0.0938 for all reflections.
