用恒温溶解度法研究了ReI3-CS(NH2)2-H2O(Re=Sm, Dy)两个三元体系在0℃时的相平衡, 体系中分别有组成为ReI3.[CS(NH2)2]2.10H2O(Re=Sm, Dy)的两个三元配合物生成,红外光谱和X射线衍射表明它们是独立的化合物, 不是各组分的混合物。本文还确定了该两配合物的制备条件及方法, 测定了它们的一些性质。

Using the solubility isotherm method, the two ternary systems ReI3-CS(NH2)2-H2O(Re=Sm, Dy) have been studied. The dithiourea adductts of Re (Re=Sm, Dy) iodide(i.e. ReI3.[CS(NH2)2]2.10H2O), containing ten water molecules, were found in the two systems. The conditions of their preparation have been determined. The melting points, density, infrared spectrums and X-ray diffracation data of the two adducts have been recorded.
