The compound described by CrCoPt2 crystallizes in the trigonal R3m space group. Cr(1) is bonded to three equivalent Co(1) and three equivalent Pt(1) atoms to form distorted CrCo3Pt3 cuboctahedra that share corners with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, corners with six equivalent Pt(2)Co3Pt9 cuboctahedra, edges with six equivalent Cr(1)Co3Pt3 cuboctahedra, edges with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, and edges with six equivalent Pt(2)Co3Pt9 cuboctahedra. Co(1) is bonded to three equivalent Cr(1), six equivalent Co(1), and three equivalent Pt(2) atoms to form distorted CoCr3Co6Pt3 cuboctahedra that share corners with six equivalent Cr(1)Co3Pt3 cuboctahedra, corners with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, edges with six equivalent Cr(1)Co3Pt3 cuboctahedra, edges with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, edges with six equivalent Pt(2)Co3Pt9 cuboctahedra, faces with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, and faces with six equivalent Pt(2)Co3Pt9 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 Co(1), three equivalent Pt(1), and six equivalent Pt(2) atoms to form distorted PtCo3Pt9 cuboctahedra that share corners with six equivalent Cr(1)Co3Pt3 cuboctahedra, corners with six equivalent Pt(2)Co3Pt9 cuboctahedra, edges with six equivalent Cr(1)Co3Pt3 cuboctahedra, edges with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, edges with six equivalent Pt(2)Co3Pt9 cuboctahedra, faces with six equivalent Co(1)Cr3Co6Pt3 cuboctahedra, and faces with six equivalent Pt(2)Co3Pt9 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
