摘要
本文根据０℃时碘化镧（ＬａＩ３）、碘化钆（ＧｄＩ３）－硫脲（ＣＳ（ＮＨ２）２）－水三元体系相平衡数据，确定了配合物ＲＥＩ３·２ＣＳ（ＮＨ２）２·１０Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｇｄ）的制备方法，并对所得配合物进行化学分析、Ｘ－射线粉末衍射、红外光谱、差热分析，测定其密度、折光指数及轴性，确定配合物结构中的配位关系。
On the basis of the phase equilibrium date of lanthanumiodide(LaI 3),gadolinium iodide(GdI 3) thiourea(CS(NH 2) 2) water(H 2O) ternary systems at 0℃,the systhesis method of REI 3·2CS(NH 2) 2·10H 2O(RE=La,Gd) have been determined,component of the complexes were determined by chemical analysis.The complexes have been studied by method of X ray powder diffraction,infrared analysis and diferential thermal analysis.The density and crystalaxis for the complexes were determined.The coordination type in the complexes was given.
