A new coordination polymer with the formula of [Co(2-mpac)2(py)·4H2O)]n (1, 2-mpac = 5-methyl-2-pyrazinecarboxylic acid, py = pyrazine) has been synthesized through hydrothermal synthesis and structurally characterized by X-ray single-crystal diffraction method. 1 exhibits a 3D supramolecular network. Crystal data: monoclinic, space group C2/m, a = 15.907(9), b = 7.104(3), c = 9.793(5), β = 95.232(8)o, V = 1102.0(10)3, Z = 2, S = 0.995, the final R = 0.0509, wR = 0.1626 for 1002 observed reflections with (I > 2σ(I)) and R = 0.0530, wR = 0.1667 for all data. In addition, elemental analysis, IR and thermalgravimetric analysis are presented.
