The material described by Ce2Pt8P crystallizes in the orthorhombic Amm2 space group. Ce(1) is bonded in a 17-coordinate geometry to two equivalent Pt(4), two equivalent Pt(5), three equivalent Pt(3), four equivalent Pt(1), four equivalent Pt(2), and two equivalent P(1) atoms. There are five inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to four equivalent Ce(1), two equivalent Pt(2), two equivalent Pt(3), and one P(1) atom. In the second Pt site, Pt(2) is bonded to four equivalent Ce(1), two equivalent Pt(1), two equivalent Pt(2), and four equivalent Pt(3) atoms to form a mixture of face, corner, and edge-sharing PtCe4Pt8 cuboctahedra. In the third Pt site, Pt(3) is bonded in a 9-coordinate geometry to three equivalent Ce(1), two equivalent Pt(1), and four equivalent Pt(2) atoms. In the fourth Pt site, Pt(4) is bonded in a 2-coordinate geometry to four equivalent Ce(1) and two equivalent P(1) atoms. In the fifth Pt site, Pt(5) is bonded in a 5-coordinate geometry to four equivalent Ce(1) and one P(1) atom. P(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Pt(5), two equivalent Pt(1), and two equivalent Pt(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
