  Rhodium(III) sulfide is the inorganic compound with the formula $Rh_2S_3.$ 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. $Rh_2Se_3$ and $Ir_2S_3$ adopt the same structure as $Rh_2S_3.$
