利用氯化锌和4-羟基吡啶在乙醇溶液中反应得到了配合物Zn(p—HPO)2Cl2(p—HPO=4-吡啶酮),并对其进行了元素分析、红外和单晶X射线的表征。配合物晶体属单斜晶系,空间群为C2/c,晶胞参数为a=1.31839(19)nm,b=1.1238(3)nm,c=0.87379(18)nm,β=106.401(11)°。V=1.2419(5)nm^3,Z=4,Mr=326.49,Dc=1.746g/cm^3,β=2.397mm^-1,F(000)=656,最终R=0.0380,ωR=0.0943。在该配合物中,4-羟基吡啶是以其共振化合物4-吡啶酮的形式参与配位,锌离子与两个4-吡啶酮配体中的氧原子和两个氯阴离子配位,形成扭曲的四面体构型,且由N—H…Cl分子间氢键构筑成二维超分子网络结构。
A novel complex of Zn (p -HPO)2 Cl2 (P -HPO = 4 -pyridone) was synthesized by the reaction of ZnCl2 · 4H2O and 4 -hydroxypyridine in an alcohol solution, and characterized by elemental analysis, IR spectrum and single crystal X -ray diffraction. The title complex belongs to monoclinic system with space group C2/c, cell parameters: a = 1.31839 ( 19 ) nm, b = 1. 1238 (3) nm, c = 0. 87379 ( 18 ) nm, β = 106. 401 ( 11 ) °. V = 1. 2419 ( 5 ) nm^3, Z =4, Mr =326. 49, Dc = 1. 746g/cm^3,μ =2. 397mm^-1 , F(000) =656, R =0. 0380, ωR =0. 0943. The Zn (Ⅱ) atom is four - coordinated by two O atoms from 4 - HPO ligands and two CI anions, displaying a distorted tetrahedral geometry. Furthermore, a 2 - D Hydrogen bonding superamolecular network is constructed via the intermolecular hydrogen bonds.
