配合物Cu(Phen)3].2C lO4.C2H5OH.0.86H2O(phen=邻啡萝啉)的结构由X-射线测定,配合物属三斜晶系,Pī空间群,晶胞参数:a=1.1359(3)nm,b=1.2955(2)nm,c=1.4495(2)nm,a=82.94(1),°β=76.14(1),°γ=67.52(1),°V=1.9124(6)nm3,Z=2.三个邻啡萝啉与铜配位形成六配位的配位阳离子,由于John-Teller效应形成变形八面体,Cu-N键键长在0.2090(3)nm至0.2208(4)nm之间。配合物由配位阳离子,两个高氯酸根,一个乙醇分子和0.86个水分子组成。配合物由Cu(phen)32 和C l04-之间的静电引力以及它们与乙醇、水之间的范德华力堆积而成。

Synthesis and structure of Copper(Ⅱ)complex [Cu(Phen)3]·2ClO4·C2H5OH·0.86H2O

The crystal and molecular structure of Cu (Phen)3]·2ClO4·C2H5OH·0.86H2O(phe＝1,10-phenanthroline) have been determined by X-ray crystallography.The complex crystallizes in triclinic system,space group Pī,with lattice parameters a＝1.1359(3)nm,b＝1.2955(2)nm,c＝1.4495(2)nm,a＝82.94(1)°,β＝76.14(1)°,γ＝67.52(1)°,V＝1.9124(6)nm3and Z＝2.The coordinated cations contain a six-coordinated copper atom chelated by three Phen ligands,and the John-Teller effect of the Cu(Ⅱ)ion results in a distorted octahedral arrangement with the six Cu-N distances ranging from 0.2090(3)to 0.2208(4)nm.In addition to the copper coordinated cation,there are two perchloride acid ions,one ethanol and 0.86 water molecules in its asymmetric unit.In the solid state,the complex is packed by electrostatic attraction and Van der Walls force among Cu(phen)32+cation,two ClO-4 canions,one ethanol and 0.86 water molecules.
