The crystal structure described by PtCr crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent Cr(1) and six equivalent Pt(1) atoms to form distorted CrCr6Pt6 cuboctahedra that share corners with twelve equivalent Cr(1)Cr6Pt6 cuboctahedra, edges with twelve equivalent Cr(1)Cr6Pt6 cuboctahedra, edges with twelve equivalent Pt(1)Cr6Pt6 cuboctahedra, faces with six equivalent Cr(1)Cr6Pt6 cuboctahedra, and faces with twelve equivalent Pt(1)Cr6Pt6 cuboctahedra.
