Rhodium(III) sulfide is the inorganic compound with the formula Rh2S3. It is an insoluble black solid, prepared by the heating a mixture of elemental rhodium and sulfur. Crystals can be grown by chemical vapor transport using bromine as the transporting agent. The structure consists of octahedral and tetrahedral Rh and S centers, respectively. No close Rh-Rh contacts are observed.[1] Rh2Se3 and Ir2S3 adopt the same structure as Rh2S3.
