摘　　要：A mononuclear Cobalt(Ⅱ) complex [CoL(H2O)2]n (H2L:4,4′,6,6′-Tetrabromo-2,2′-[ethylenedioxybis(nitrilomethylidyne)]diphenol), has been synthesized and structurally characterized by elemental analysis, IR and X-ray diffraction single crystal structure analysis. The crystal of the complex belongs to monoclinic space group P21/c with a=2.516 8(3) nm, b=1.023 43(18) nm, c=0.789 17(14) nm, β=91.375(2)°, V=2.032 1(5) nm3, Z=4, Dc=2.317 Mg·m-3, μ(Mo Kα)=8.747 mm-1, F(000)=1 356, R1=0.049 7, wR2=0.110 4. The crystal structure of [CoL(H2O)2]n indicates that the complex consists of one cobalt(Ⅱ) atom, one L2-unit and two coordinated water molecules, and the coordination number of the cobalt(Ⅱ) atom is six. One-dimensional chain supramolecular structure is formed by intermolecular hydrogen bonds and π-π stacking of neighboring benzene rings.
