The crystal structure described by CrPt4 crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent Pt(1) atoms to form distorted CrPt6 cuboctahedra that share corners with six equivalent Pt(2)Pt12 cuboctahedra, edges with six equivalent Cr(1)Pt6 cuboctahedra, and edges with six equivalent Pt(2)Pt12 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1) and three equivalent Pt(2) atoms. In the second Pt site, Pt(2) is bonded to three equivalent Pt(1) and nine equivalent Pt(2) atoms to form PtPt12 cuboctahedra that share corners with three equivalent Cr(1)Pt6 cuboctahedra, corners with six equivalent Pt(2)Pt12 cuboctahedra, edges with three equivalent Cr(1)Pt6 cuboctahedra, edges with twelve equivalent Pt(2)Pt12 cuboctahedra, and faces with twelve equivalent Pt(2)Pt12 cuboctahedra. is represented by the CIF card [CIF]
