摘　　要：本文制备了二(N,N-二甲基甲酰胺)合高氯酸N,N,N′,N′-四[(1′-正丁基-2′-苯并咪唑)甲基]-1,2-环己二胺合铜(Ⅱ),[Cu(NBUOCTB)](ClO_4)_2·2DMF.测定表明其晶体属正交晶系,空间群为P_(ban),α=1.2553(2),b=2.0022(8),c=2.5687(5)nm,V=6.456(4)nm^3,M_r=1267.84,Z=4,Dx=1.304g/cm^3,μ=4.81cm^(-1),F(000)=2684.利用TG-DTG技术研究了配合物的热分解过程.采用积分法和微分法相结合方案,对实验数据进行分析.推断第一步热分解过程为成核和生长机理(n=1),符合Avrami-Erofeev方程;第二步热分解过程为二级化学反应机理.The coordination compound of Cu(Ⅱ) with N,N,.N',N'-tetra[ (1 '-n-butyl-2'-benzimidazol) methyl]-/rani-l,2-diaminocyclohexane (NBUOCTB), [Cu(NBUOCTB)](C1O4)2 · 2DMF, was prepared. The compound crystallizes in space group Pban with a =1.2553(2), b = 2.0022(8), c = 2.5687(5)nm, Z = 4. The thermal decomposition process of the compound has also been studied using TG-DTG techniques under non-isothermal condition. The experimental data were analyzed through the combination of integral and differential methods. The first thermal decomposition stage belongs to ' Coring and Growth (n = 1)' mechanism and conforms to Avrami-Erofeev equation. The second stage is 'Two-order Chemical Reaction'.
