Single crystals of tri-chlorido-sulfonium-(IV) hexa-chlorido-uranate(V) were obtained from the reaction of uranium(IV) chloride with an excess of disulfur dichloride and studied by single-crystal X-ray diffraction. In comparison with the structure model reported previously [Sawodny (1983 ▸). , 81-88.], the lattice parameters and fractional atomic coordinates were determined to a much higher precision, leading overall to an improved structure model. The ionic compound contains trigonal-pyramidal (SCl) cations and slightly distorted octa-hedral [UCl] anions. The structure was refined as an inversion twin with a twin ratio of 4.4:1.
通过四氯化铀与过量的二氯化二硫反应得到了六氯铀酸（V）三氯化锍（IV）单晶，并采用单晶X射线衍射对其进行了研究。与之前报道的结构模型[Sawodny (1983 ▸). , 81 - 88.]相比，晶格参数和原子分数坐标的测定精度更高，从而总体上得到了一个改进的结构模型。该离子化合物包含三角锥型的（SCl）阳离子和略微畸变的八面体[UCl]阴离子。该结构被精修为一个孪晶比为4.4:1的倒易孪晶。
