The crystal structure described by Rh3Os is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Os(1) is bonded to twelve equivalent Rh(1) atoms to form OsRh12 cuboctahedra that share corners with six equivalent Os(1)Rh12 cuboctahedra, corners with twelve equivalent Rh(1)Os4Rh8 cuboctahedra, edges with eighteen equivalent Rh(1)Os4Rh8 cuboctahedra, faces with eight equivalent Os(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Os4Rh8 cuboctahedra. Rh(1) is bonded to four equivalent Os(1) and eight equivalent Rh(1) atoms to form RhOs4Rh8 cuboctahedra that share corners with four equivalent Os(1)Rh12 cuboctahedra, corners with fourteen equivalent Rh(1)Os4Rh8 cuboctahedra, edges with six equivalent Os(1)Rh12 cuboctahedra, edges with twelve equivalent Rh(1)Os4Rh8 cuboctahedra, faces with four equivalent Os(1)Rh12 cuboctahedra, and faces with sixteen equivalent Rh(1)Os4Rh8 cuboctahedra. is represented by the CIF card [CIF]
