合成了一个单核配合物[Zn(H20).(p-OPA)2·2H2O](pOPA-=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P2,/e,晶胞参数为a=12.427(3)А,b=12.833(3)A,c=6.7816(14)A,β=98.62(3)°.y=1069.3(4)А^3,Z=2,M,=513.75,Do=1.596g/cm^3,F(000)=536,最终R=0.0272,wR=0.0734.Zn(Ⅱ)原子处于反演中心并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 mononuclear Zn( Ⅱ) complex of [Zn(H20)6(p-OPA)2·2H2O] (p-OPA- = 4-oxo-l(4H)- pyridineacetate) was synthesized and characterized by elemental analysis and single crystal X-ray diffraction. This complex belongs to monoclinic system with space group P21/c, a=12.427 (3)A, b=12.833(3)A., c= 6.7816(14)A, β= 99.62(3)A.. V= 1069.3(4)A3 , Z=2,Mr=513.75, De= 1.596g/cm^3, F(000)= 536, R= 0.0272, wR= 0.0734. The Zn(Ⅱ) atom resided in the inversion centre is coordinated by six water molecules, having a nearly ideal octahedron geometry. The 4-oxo-1(4H)-pyridineacetate monoanion is free state as counterions. Furthermore, a three-dimensional hydrogen-bond supramolecular framework is formed by intermolecular hydrogen bonds and eletrostatic force interactions between the anions and cations.
