摘要 配位聚合物由于在催化材料、磁性材料和光学材料等领域中具有广泛的应用价值。近年来已引起人们的极大关注。含氮、含氧桥联配体是合成具有不同拓扑结构的配位聚合物的重要原料.除此以外.氢键也是构筑配位聚合物的重要途经。 A complex [Ni(α-furacrylic acid)2(4,4'-bipy)(H2O)5]n with α-furacrylic acid, 4,4'-bipy and Nickel perchlorate has been synthesized by means of hydrothermal way and characterized. Crystal data for this complex: monoclinic, space group P21/c, α=l. 122 2(2) nm, b=1.084 1(2) nm, c=1.081 6(2) nm, β=98.37(3)^o, V=1.301 8(5) nm^3, Dc=1.524 g·cm^-3, Z=2,μ(Mo Kα)=0.813 mm^-1, F(000)=624, S=1.073, R1=0.041 2, wR2=0.093 4. The crystal structure shows that the Nickel(n) ion is coordinated with two nitrogen atoms of two 4,4'-bipy molecules and four oxygen atoms from four water molecules, respectively, giving a distorted octahedral coordination geometry. Adjacent Nickel(n) ion are bridged by 4,4'-bipy groups and the adjacent Ni(Ⅱ)...Ni(ll) distance is 1.122 2 nm. The Nickel(n) ion isn't coordinated with α-furacrylic acid .The complex molecules form 2D structure through hydrogen bonds. The cyclic voltametric behavior of the complex was also investigated.
