铜配合物[CuL_2Cl_2]·4H_2O的合成和晶体结构(L=3-乙基-4-对甲氧苯基-5-(2-吡啶基)-1,2,4-三氮唑)

A new copper(Ⅱ)complex,CuL_2Cl_2]·4H_2O,L=3-ethyl-4-(p-methoxyphenyl)-5-(2-pyridyl)-1,2,4-triazole],was synthesized and characterized by X-ray crystallography and infrared spectroscopy.The complex crystallizes in triclinic system with space group P(1),α=0.843 9(7)nm,b=0.965 5(8)nm,c=1.093 6(8)nm,α=84.026(19)°,β=82.33(2)°,γ=89.167(19)°,V=0.878 3(12)nm~3,Z=1 with final R=0.033 8.The copper atom lies in a distorted octahedral environment with two bidentate chelating ligands(L)in the equatorial plane and two Cl~- ions in the axial positions.The ligand L coordinates via one triazole nitrogen and one pyridine nitrogen atom.The molecules are stabilized by intermolecular hydrogen bonds in the crystal lattice.CCDC:705817.
