合成了一个新的配合物[Ni(p-CPOAH2)·(H2O)4](p-CPOAH-=4-羧基苯氧乙酸根),并对其进行了元素分析和单晶X射线的表征。结果表明:配合物晶体属三斜晶系,空间群为P1,晶胞参数为a=0.490 53(10)nm,b=0.56878(11)nm,c=1.8447(4)nm,α=93.88(3)°,β=91.86(3)°,γ=95.69(3)°,V=0.51057(18)nm3,Z=1,Mr=521.07,Dc=1.695g·cm-3,μ=1.027mm-1,F(000)=270,最终R=0.0360,wR=0.0912。两个配体的氧乙酸上的羧基氧原子和四个配位水分子与镍原子配位,Ni(Ⅱ)原子为六配位八面体构型,且由分子间氢键形成了三维超分子氢键网络结构。
A new complex [Ni (p-CPOAH2) · (H2O) 4] (p-CPOAH- = 4-carboxy phenoxyacetate) was synthesized and characterized by elemental analysis and single crystal X-ray diffraction. The results show that the crystal of the complex belongs to the triclinic system with the space group P1. The unit cell parameters are a = 0.490 53 (10) nm, b = 0.56878 (11) nm, c = 1.8447 (4) nm and α = 93.88 3 = 1, γ = 95.69 (3) °, V = 0.51057 (18) nm3, Z = 1, Mr = 521.07, Dc = 1.695 g · cm-3, μ = 1.027 mm- 1, F (000) = 270, final R = 0.0360, wR = 0.0912. The two oxygen atoms of the two ligands, the oxygen atoms of the carboxyl group and the four coordination water molecules, are coordinated with the nickel atom. The Ni (Ⅱ) atom is a six-coordinated octahedron and the three-dimensional supramolecular Hydrogen bond network structure.
