The compound described by Co3Pt is beta-derived structured and crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent Co(1) and six equivalent Co(2) atoms to form CoCo12 cuboctahedra that share corners with six equivalent Co(1)Co12 cuboctahedra, corners with twelve equivalent Pt(1)Co6Pt6 cuboctahedra, edges with six equivalent Co(1)Co12 cuboctahedra, edges with twelve equivalent Co(2)Co9Pt3 cuboctahedra, faces with two equivalent Pt(1)Co6Pt6 cuboctahedra, faces with six equivalent Co(1)Co12 cuboctahedra, and faces with twelve equivalent Co(2)Co9Pt3 cuboctahedra. In the second Co site, Co(2) is bonded to three equivalent Co(1), six equivalent Co(2), and three equivalent Pt(1) atoms to form CoCo9Pt3 cuboctahedra that share corners with eighteen equivalent Co(2)Co9Pt3 cuboctahedra, edges with six equivalent Co(1)Co12 cuboctahedra, edges with six equivalent Co(2)Co9Pt3 cuboctahedra, edges with six equivalent Pt(1)Co6Pt6 cuboctahedra, faces with six equivalent Co(1)Co12 cuboctahedra, faces with six equivalent Pt(1)Co6Pt6 cuboctahedra, and faces with eight equivalent Co(2)Co9Pt3 cuboctahedra. Pt(1) is bonded to six equivalent Co(2) and six equivalent Pt(1) atoms to form PtCo6Pt6 cuboctahedra that share corners with six equivalent Pt(1)Co6Pt6 cuboctahedra, corners with twelve equivalent Co(1)Co12 cuboctahedra, edges with six equivalent Pt(1)Co6Pt6 cuboctahedra, edges with twelve equivalent Co(2)Co9Pt3 cuboctahedra, faces with two equivalent Co(1)Co12 cuboctahedra, faces with six equivalent Pt(1)Co6Pt6 cuboctahedra, and faces with twelve equivalent Co(2)Co9Pt3 cuboctahedra. is represented by the CIF file [CIF]
