The material structure described by Ce3Pt7Sb4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 12-coordinate geometry to two equivalent Pt(1), two equivalent Pt(2), two equivalent Pt(3), two equivalent Pt(4), two equivalent Sb(1), and three equivalent Sb(2) atoms. In the second Ce site, Ce(2) is bonded to two equivalent Pt(3), four equivalent Pt(1), four equivalent Pt(2), two equivalent Sb(1), and four equivalent Sb(2) atoms to form distorted CeSb6Pt10 cuboctahedra that share corners with four equivalent Pt(4)Ce4Sb2Pt6 cuboctahedra, faces with two equivalent Ce(2)Sb6Pt10 cuboctahedra, and faces with two equivalent Pt(4)Ce4Sb2Pt6 cuboctahedra. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), one Pt(2), one Sb(2), and three equivalent Sb(1) atoms. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), one Pt(1), two equivalent Pt(3), two equivalent Pt(4), one Sb(2), and two equivalent Sb(1) atoms. In the third Pt site, Pt(3) is bonded in a 6-coordinate geometry to one Ce(2), two equivalent Ce(1), one Pt(4), two equivalent Pt(2), and three equivalent Sb(2) atoms. In the fourth Pt site, Pt(4) is bonded to four equivalent Ce(1), two equivalent Pt(3), four equivalent Pt(2), and two equivalent Sb(1) atoms to form distorted PtCe4Sb2Pt6 cuboctahedra that share corners with four equivalent Ce(2)Sb6Pt10 cuboctahedra, faces with two equivalent Ce(2)Sb6Pt10 cuboctahedra, and faces with two equivalent Pt(4)Ce4Sb2Pt6 cuboctahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), one Pt(4), two equivalent Pt(2), and three equivalent Pt(1) atoms. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), one Pt(1), one Pt(2), and three equivalent Pt(3) atoms. is represented by the CIF card [CIF]
