采用三种不同的方法,用邻羧基苯甲醛水杨酰腙与硝酸镧反应,制得新型稀土镧配合物,经元素分析、化学分析并且结合热分析确定了其组成为La(C_(15)H_(11)N_2O_4)(C_(15)H_(10)N_2O_4)·2H_2O。利用摩尔电导测定、红外光谱、氢谱等手段推测了配合物的结构。根据TG-DTG曲线研究了配合物的热分解过程。
A new rare earth lanthanum complex was synthesized by three different methods using ortho-carboxybenzaldehyde salicyloylhydrazone and lanthanum nitrate. The elemental analysis, chemical analysis and thermal analysis showed that La (C_ (15) H_ 11) N_2O_4) (C_ (15) H_ (10) N_2O_4) · 2H_2O. The structure of the complex was presumed by means of molar conductivity detection, infrared spectroscopy and hydrogen spectrum. The thermal decomposition of the complex was studied by TG-DTG curve.
