The material structure described by CePt4Ga crystallizes in the hexagonal P-6m2 space group. Ce(1) is bonded in a 18-coordinate geometry to three equivalent Pt(1), twelve equivalent Pt(2), and three equivalent Ga(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to three equivalent Ce(1), six equivalent Pt(2), and three equivalent Ga(1) atoms to form distorted PtCe3Ga3Pt6 cuboctahedra that share corners with nine equivalent Ga(1)Ce3Pt9 cuboctahedra, corners with twelve equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra, edges with six equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, faces with two equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, faces with three equivalent Ga(1)Ce3Pt9 cuboctahedra, and faces with eighteen equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra. In the second Pt site, Pt(2) is bonded to four equivalent Ce(1), two equivalent Pt(1), four equivalent Pt(2), and two equivalent Ga(1) atoms to form distorted PtCe4Ga2Pt6 cuboctahedra that share corners with four equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, corners with four equivalent Ga(1)Ce3Pt9 cuboctahedra, corners with sixteen equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra, edges with ten equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra, faces with six equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, faces with six equivalent Ga(1)Ce3Pt9 cuboctahedra, and faces with ten equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra. Ga(1) is bonded to three equivalent Ce(1), three equivalent Pt(1), and six equivalent Pt(2) atoms to form distorted GaCe3Pt9 cuboctahedra that share corners with nine equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, corners with twelve equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra, edges with six equivalent Ga(1)Ce3Pt9 cuboctahedra, faces with two equivalent Ga(1)Ce3Pt9 cuboctahedra, faces with three equivalent Pt(1)Ce3Ga3Pt6 cuboctahedra, and faces with eighteen equivalent Pt(2)Ce4Ga2Pt6 cuboctahedra. is represented by the CIF file [CIF]
