Iridium disulfide is the binary inorganic compound with the formula IrS2. Prepared by the direct reaction of the elements, the compound adopts the pyrite crystal structure at high pressure.[1] At normal atmospheric pressures, an orthorhombic polymorph is observed.[2]. The high- and low-pressure forms both feature octahedral Ir centers, but the S–S distances are pressure dependent.[3] Although not practical, IrS2 is a highly active catalyst for hydrodesulfurization.[4]
