The material structure described by OsIr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Os(1) is bonded to six equivalent Os(1) and six equivalent Ir(1) atoms to form OsIr6Os6 cuboctahedra that share corners with eighteen equivalent Os(1)Ir6Os6 cuboctahedra, edges with six equivalent Os(1)Ir6Os6 cuboctahedra, edges with twelve equivalent Ir(1)Ir6Os6 cuboctahedra, faces with eight equivalent Os(1)Ir6Os6 cuboctahedra, and faces with twelve equivalent Ir(1)Ir6Os6 cuboctahedra.
