摘要
以吡蚜酮为配体,合成了1个新配合物[Zn(L)2(Ac)2(H2O)2].4H2O(I)(L=pymetrozine).用X-射线单晶衍射结构分析方法测定了配合物的晶体结构,该配合物为单核结构,Zn2+分别与2个吡蚜酮分子吡啶环的氮原子、2个水分子中的2个氧原子以及2个醋酸根的2个氧原子形成扭曲的八面体配位几何构型,分子间通过氢键作用构筑成三维超分子网络结构.配合物属于三斜晶系,空间群为p-1,a=7.628(2),b=9.484(3),c=12.440(4),α=106.062(4)°,β=101.627(4)°,γ=95.447(4)°,V=836.2(4)3,Z=1,R1=0.0427,wR2=0.1037.
A new complex [Zn(L)2(Ac)2(H20)2]4H20 (I) (L--pymetrozine) is obtained and structurally deter- mined by X-ray single crystal diffraction. The complex I is a monuclear structure, the complex adopts a distorted octahedral coordinated geometry formed by two N atoms and four O atoms, of which two N atoms come from pymetrozine ligands, two O atoms from H20 and the other two O atoms from acetates. The molecules are further connected to a three-dimensional supramolecular network by hydrogen bonding contacts. Crystal data for the complex are given as follows: triclinic, space group p-l, a=7.628(2) A, b=9.484(3) A, c=12.440(4) A, a= 106.062(4) o, β= 101.627(4) , y=95.447(4) o, V=836.2(4) A3, Z=1, R1=0.0427, wR2=0.1037.
