The compound described by CePt2Sn2 crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Sn(2) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Ce(1) and four equivalent Pt(2) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Pt(2), and four equivalent Pt(1) atoms. is represented by the CIF file [CIF]
