2-(1H-1,2,4-三氮唑)乙酸Cu(Ⅱ)配合物的水热合成、晶体结构及性质

A copper(Ⅱ) complex CuL2] L=2-(1H-1,2,4-triazol-1-yl)acetic acid] has been synthesized by means of hydrothermal method, and characterized by elemental analysis, IR spectra and X-ray diffraction. Crystal data for this complex: monoclinic, space group P21/n, a=0.481 3(2) nm, b=1.151 1(6) nm, c=0.993 9(5) nm, β=100.528(8)°, V=0.541 4(5) nm3, Z=2, F(000)=318, Dc=1.937 g·cm-3, Final GooF=1.109, R1=0.027 6, wR2=0.075 6. The crystal structure shows the copper(Ⅱ) atom is six-coordinated by two triazole nitrogen atom and four carboxylate group oxygen atom from four distinct L- ligand, thereby forming a 2D network structure. The cyclic voltammetric behavior of the complex was described.
