The crystal structure described by Ce2(PtSi)3 crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded to four equivalent Ce(1), one Pt(1), and one Si(1) atom to form distorted CeCe4SiPt octahedra that share corners with four equivalent Ce(1)Ce4SiPt octahedra, edges with four equivalent Ce(1)Ce4SiPt octahedra, and edges with four equivalent Si(1)CeSi4Pt octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted linear geometry to one Ce(1) and one Si(2) atom. In the second Pt site, Pt(2) is bonded in a distorted linear geometry to two equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one Ce(1), one Pt(2), and four equivalent Si(1) atoms to form distorted SiCeSi4Pt octahedra that share corners with five equivalent Si(1)CeSi4Pt octahedra, edges with four equivalent Ce(1)Ce4SiPt octahedra, and edges with four equivalent Si(1)CeSi4Pt octahedra. The corner-sharing octahedra are not tilted. In the second Si site, Si(2) is bonded in a distorted linear geometry to two equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
