摘要：

Re6S8Cl2 single crystals have been synthesized by chemical vapour transport with chlorine as transporting agent. Structure analysis revealed that the material is isomorphous with Re6S8Br2 and Re6Se8Br2 but not with the lamellar ReSe8Cl2. The thermal stability of this semiconducting rhenium cluster compound was simulated as a function of vapour phase composition by thermochemical calculations in the ternary system Re - S - Cl at temperatures 1000, 1200 and 1400 K. Predominance-area phase diagrams indicate that Re6S8Cl2 can coexist with Re and ReS2 depending on the vapour pressure ratios of S2/S2Cl2 and Cl2/Re3Cl9.
