2D氢键网络镍配合物{[Ni(4，4′-bipy)(H2O)4]·(α-furacrylic acid)2·(H2O)}n的水热合成、晶体结构及电化学性质

A complex [Ni(α-furacrylic acid)₂(4，4′-bipy)(H₂O)₅]_n with α-furacrylic acid， 4，4′-bipy and Nickel perchl-orate has been synthesized by means of hydrothermal way and characterized. Crystal data for this complex: monoclinic， space group P2₁/c， a=1.122 2(2) nm， b=1.084 1(2) nm， c=1.081 6(2) nm， β=98.37(3)°， V=1.301 8(5) nm³， D_c=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(Ⅱ) 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(Ⅱ) ion are bridged by 4，4′-bipy groups and the adjacent Ni(Ⅱ)…Ni(Ⅱ) distance is 1.122 2 nm. The Nickel(Ⅱ) 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.
