The title complex [Cu (bpy) (H2O) (mal)]. H2O (bpy = 2,2’-bipyridyl, mal = malonate) was synthesized by solution method. The crystal structure of the complex was determined by X-ray diffractometry. The crystallographic data are as follows: trisprime, P-1, a = 7.132 1, b = 10.404 2, c = 10.694 2, = 105.85 (3) °, β = 104.53 (3) °, γ = 105.28 (3) °, V = 690.4 (2) (3), Dc = 1.721 g.cm-3, Z = In the title compound, the coordination number of Cu (Ⅱ) ion in the center is 5, forming the tetragonal pyramid coordination mode of CuN2O3. And its infrared spectroscopy, elemental analysis, powder X-ray diffraction, differential thermal, magnetic characterization. The 3D topological analysis of the complex can simplify the (4,6) -double-node fsc topology network. The complex can follow the Weiss theorem χm (T-0.27) = 0.85cm3.K.mol-1 in the range of 2 ~ The test results show that there is ferromagnetic effect between Cu2 + ions.
