摘要
以氧化镉,邻菲咯啉(phen)和3-羟基-1-金刚烷甲酸(C_(10)H_(15)(OH)COOH)为原料,水热合成配合物[Cd(C_(10)H_(15)(OH)COO)_2(phen)_2]·C_(10)H_(15)(OH)COOH·5H_2O。用元素分析、红外光谱、1HNMR核磁共振、热重分析以及单晶衍射等手段进行表征,测定了它的晶体结构;晶体属于三斜晶系,空间群P1。测定了配合物的热分解情况,并用TG-DTG方法研究了热分解动力学机理。
A Cadmium(Ⅱ) complex [Cd(C10H15(OH)COO)2(phen)2]-C10H15(OH)COOH-5H2O was synthesized by hydrothermal synthesis from cadmium oxide, phenanthroline and 3-hydroxy-1-adamantane acid (C10H15(OH)COOH). It was characterized by elemental analysis,IR and ^1H NMR spectra, TG-DTG. Its crystal structure was determined by single crystal X-ray diffraction method. The complex, C57H72CdN4O14, crystallizes in the triclinic system, space group P1 with a=1.258 22(6) nm, b=1.309 36(6) nm, c=1.858 61(8) nm, α=77.032(2)°, β=81.745(2)°, γ=62.109(2)°, V= 2.6346(2) nm^3, Z=2, Mr=1149.6, F(000)=1204, Dc=1.449 Mg.m^-3,μ(Mo Ka)=0.487 mm^-1. The kinetic parameters were obtained from the analysis of TG curve by integral and differential methods. The functions of thermal decomposition reaction mechanism are: f(α)=3/2(1 -α)4/3[ 1/(1 -α)1/3- 1]^-1, g(α)=[ 1/(1 -α)^1/3 -1]^1/2, kinetic compensation effect equation lnA1=2.965 8E1+ 17.72; lnA 2=2.983 9E2+2.359 5.
