采用固态化学技术合成了Cs2Mo6Br14(1)和Cs2Mo6I14(2)，并通过单晶X射线衍射对其结构进行了表征。它们在 P3´1c 空间群 (Nr. 163) 中结晶，具有以下晶格参数：a = 10.1925(1) A，c = 15.0690(3) A，Z = 2（对于 1）； a = 10.804(5) A, c = 16.258(5) A, Z = 2 for 2。这些卤化物簇的结构与 Cs2Mo6Cl8Br6 的结构相关，由离散的 [(Mo6Xi8)Xa6]2- 阴离子单元 (X = Br, I) 根据六方密堆积排列堆叠而成。在本工作中，将证明和讨论卤素对铯位点的影响。此外，还将提出一种以Cs2Mo6X14为原料制备(TBA)2Mo6Xi8Xa6的简单高产率制备方法。
Cs2Mo6Br14(1) and Cs2Mo6I14(2) have been synthesized by solid state chemistry techniques and structurally characterized by single crystal X-ray diffraction. They crystallize in the P3¯1c space group (Nr. 163) with the following lattice parameters: a = 10.1925(1) A, c = 15.0690(3) A, Z = 2 for 1; a = 10.804(5) A, c = 16.258(5) A, Z = 2 for 2. These clusters halides, whose structures are related to that of Cs2Mo6Cl8Br6, are built up from discrete [(Mo6Xi8)Xa6]2- anionic units (X = Br, I) stacked according to an hexagonal close-packing arrangement. In the present work, the influence of the halogen on the cesium sites will be evidenced and discussed. Furthermore, a simple high yield preparation method of (TBA)2Mo6Xi8Xa6 will be proposed starting from Cs2Mo6X14.
