合成了一个新的配合物[Mg(H2O)6](p-OPA)2.2H2O(p-OPA-=4-氧-1(4H)-吡啶乙酸根),并对其进行了元素分析和单晶X射线的表征。配合物晶体属单斜晶系,空间群为P 21/c,晶胞参数为a=1.2561(3)nm,b=1.2947(3)nm,c=0.67885(14)nm,β=99.32(3)°,V=1.0895(4)nm3,Z=2,Mr=472.69,Dc=1.441g/cm3,μ=0.154mm-1,F(000)=500,最终R=0.0525,wR=0.1398。Mg(Ⅱ)原子与六个水分子配位形成八面体构型,4-氧-1(4H)-吡啶乙酸根作为抗衡离子,配阳离子与阴离子之间通过静电吸引和氢键作用形成了三维氢键超分子网络结构。
A new complex [Mg (H2O) 6] (p-OPA) 2.2H2O (p-OPA- = 4-oxo-1 (4H) -pyridineacetate) was synthesized and characterized by elemental analysis and single Characterization of crystalline X-rays. The complex crystal belongs to the monoclinic system with a space group of P 21 / c and unit cell parameters of a = 1.2561 (3) nm, b = 1.2947 (3) nm, c = ) °, V = 1.0895 (4) nm3, Z = 2, Mr = 472.69, Dc = 1.441 g / cm3, μ = 0.154 mm- 1, F (000) = 500, final R = 0.0525, wR = 0.1398. The Mg (Ⅱ) atom coordinated with six water molecules to form an octahedral configuration. The 4-oxo-1 (4H) -pyridine acetate was used as the counterion. The electrostatic attraction and hydrogen bonding between the cation and the anion formed a three-dimensional Hydrogen bond supramolecular network structure.
