【 摘 要 】

A new coordination polymer, [Ni(bpy)(acetato)2]n (bpy = 4,4'-bipyridine), was synthesized and characterized by X-ray single-crystal structural analysis. For the complex: C14H14N2NiO4, M r = 332.98, triclinic, space group P-1, a = 8.0538(16) Å, b = 9.1680(18) Å, c = 10.659(2) Å, α = 109.80(3)°, β = 99.90(3)°, γ = 101.81(3)°, V= 699.5(2) Å3, Z = 2, Dc = 1.581g•cm-3, μ = 1.403mm-1, F(000) = 344, and final R 1 = 0.0603, ωR 2 = 0.1730. The Ni(II) ion adopts a distorted octahedral geometry coordinated by two N atoms and four O atoms. The Ni(II) complex forms 1D chain structure 2D layered structure by the bridge of 4,4'-bipyridine and acetato.
