The structure described by CePtSi2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Pt(1), four equivalent Si(2), and six equivalent Si(1) atoms. Pt(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted single-bond geometry to six equivalent Ce(1), one Pt(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 4-coordinate geometry to four equivalent Ce(1) and four equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
