The material described by Pt3Os crystallizes in the trigonal R-3m space group. Os(1) is bonded to six equivalent Os(1) and six equivalent Pt(1) atoms to form OsOs6Pt6 cuboctahedra that share corners with six equivalent Os(1)Os6Pt6 cuboctahedra, corners with six equivalent Pt(2)Pt12 cuboctahedra, edges with six equivalent Os(1)Os6Pt6 cuboctahedra, edges with six equivalent Pt(2)Pt12 cuboctahedra, edges with twelve equivalent Pt(1)Os3Pt9 cuboctahedra, faces with six equivalent Os(1)Os6Pt6 cuboctahedra, and faces with twelve equivalent Pt(1)Os3Pt9 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to three equivalent Os(1), three equivalent Pt(2), and six equivalent Pt(1) atoms to form PtOs3Pt9 cuboctahedra that share corners with twelve equivalent Pt(1)Os3Pt9 cuboctahedra, edges with six equivalent Os(1)Os6Pt6 cuboctahedra, edges with six equivalent Pt(2)Pt12 cuboctahedra, edges with twelve equivalent Pt(1)Os3Pt9 cuboctahedra, faces with six equivalent Os(1)Os6Pt6 cuboctahedra, faces with six equivalent Pt(1)Os3Pt9 cuboctahedra, and faces with six equivalent Pt(2)Pt12 cuboctahedra. In the second Pt site, Pt(2) is bonded to six equivalent Pt(1) and six equivalent Pt(2) atoms to form PtPt12 cuboctahedra that share corners with six equivalent Os(1)Os6Pt6 cuboctahedra, corners with six equivalent Pt(2)Pt12 cuboctahedra, edges with six equivalent Os(1)Os6Pt6 cuboctahedra, edges with six equivalent Pt(2)Pt12 cuboctahedra, edges with twelve equivalent Pt(1)Os3Pt9 cuboctahedra, faces with six equivalent Pt(2)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Os3Pt9 cuboctahedra. is represented by the CIF card [CIF]
