Rhodium(III) sulfide is the inorganic compound with the formula Rh<sub>2</sub>S<sub>3</sub>. 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. Rh<sub>2</sub>Se<sub>3</sub> and Ir<sub>2</sub>S<sub>3</sub> adopt the same structure as Rh<sub>2</sub>S<sub>3</sub>.
