中间价态的钼在饱和了氯化氢的乙醇介质中具有形成三核簇的倾向。在通人硫化氢的情况下,得到了两种具有三重硫桥的三核原子簇化合物,其化学式分别为(C_3H_7S_2)_3[Mo_3S_2Cl_9]和(C_3H_7S_2)_3[Mo_3S_7Cl_7]。在合成三核钼簇合物的过程中,我们发现,有些合成产物中,往往有其他晶体与三核簇合物伴生在一起,我们推测可能是双核簇合物。为了验证这一推测,我们选择具有代表性的化合物(C_5H_7S_2)_3[Mo_2Cl_9]进行晶体结构分析。
The intermediate valence molybdenum has the tendency to form triple-core clusters in an ethanolic medium saturated with hydrogen chloride. In the case of hydrogen sulfide, two kinds of tri-nuclear cluster compounds with triple sulfur bridges were obtained, and their chemical formulas were (C_3H_7S_2) _3 [Mo_3S_2Cl_9] and (C_3H_7S_2) _3 [Mo_3S_7Cl_7]. In the process of synthesizing trinuclear molybdenum clusters, we find that some of the synthesized products often have other crystals associated with trinuclear clusters, and we speculate that they may be binuclear clusters. In order to test this hypothesis, we chose the representative compound (C_5H_7S_2) _3 [Mo_2Cl_9] for crystal structure analysis.
