摘要
合成了邻香兰素（２－羟基－３－甲氧基苯甲醛）与邻氨基苯甲酸Ｓｃｈｉｆｆ碱铜（Ⅱ）配合物，测定了其晶体结构并研究了其热稳定性。晶体Ｃ_（３０）Ｈ_（２８）Ｃｕ_２Ｎ_２Ｏ_（１１）属正交晶系，空间群Ｐｃａｎ，晶胞参数：ａ＝１．０３４７（４）ｎｍ，ｂ＝１．５４９３（７）ｎｍ，ｃ＝１．７４４１（３）ｎｍ，Ｖ＝２．７９５９ｎｍ~３，Ｍ＝７１９．６４，Ｚ＝４。结构解析最终的一致性因子Ｒ＝０．０４７，Ｒｗ＝０．０４９，热分解反应动力学方程式为：ｄα／ｄｔ＝Ａ·ｅ^（－Ｅ／ＲＴ）·３（１－α）^（２／３）；其补偿效应数学表达式为：１ｎＡ＝０．２８５８Ｅ＋０．４０４５。
The complex [Cu(L)(H_2O)]_2·H_2O (L=3-methoxysalicylideneimino benzoate)was synthesized. The complex crystallizes in an orthorhombic system. space group is Pcan,cell parameters: a=1. 0347(4) nm,b=1. 5493(7) nm, c=1.7441(3) nm,Z=4,with R=0. 047,Rw=0. 049. The kinetic parameters were obtained from the analysis of the TG-DTG curves by integral and differential method. The possible reaction mechanism is suggested by comparison of the kinetic parameters.The kinetic eqution may be exprested as dα/dt=A·e￣(-E/RT)·3(1-α)￣(2/3) The mathematical expression of the kinetic compensation effect of the thermal decomposition reaction has also been obtained.
