Re3Pt crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to six equivalent Re(1) and six equivalent Re(2) atoms to form ReRe12 cuboctahedra that share corners with six equivalent Re(1)Re12 cuboctahedra, corners with twelve equivalent Pt(1)Re6Pt6 cuboctahedra, edges with six equivalent Re(1)Re12 cuboctahedra, edges with twelve equivalent Re(2)Re9Pt3 cuboctahedra, faces with two equivalent Pt(1)Re6Pt6 cuboctahedra, faces with six equivalent Re(1)Re12 cuboctahedra, and faces with twelve equivalent Re(2)Re9Pt3 cuboctahedra. In the second Re site, Re(2) is bonded to three equivalent Re(1), six equivalent Re(2), and three equivalent Pt(1) atoms to form ReRe9Pt3 cuboctahedra that share corners with eighteen equivalent Re(2)Re9Pt3 cuboctahedra, edges with six equivalent Re(1)Re12 cuboctahedra, edges with six equivalent Re(2)Re9Pt3 cuboctahedra, edges with six equivalent Pt(1)Re6Pt6 cuboctahedra, faces with six equivalent Re(1)Re12 cuboctahedra, faces with six equivalent Pt(1)Re6Pt6 cuboctahedra, and faces with eight equivalent Re(2)Re9Pt3 cuboctahedra. Pt(1) is bonded to six equivalent Re(2) and six equivalent Pt(1) atoms to form PtRe6Pt6 cuboctahedra that share corners with six equivalent Pt(1)Re6Pt6 cuboctahedra, corners with twelve equivalent Re(1)Re12 cuboctahedra, edges with six equivalent Pt(1)Re6Pt6 cuboctahedra, edges with twelve equivalent Re(2)Re9Pt3 cuboctahedra, faces with two equivalent Re(1)Re12 cuboctahedra, faces with six equivalent Pt(1)Re6Pt6 cuboctahedra, and faces with twelve equivalent Re(2)Re9Pt3 cuboctahedra.
