The structure described by Ce2PtNiSn2 crystallizes in the orthorhombic Pmc2_1 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), four equivalent Ni(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. In the second Ce site, Ce(2) is bonded in a 12-coordinate geometry to four equivalent Pt(1), two equivalent Ni(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Sn(1), and two equivalent Sn(2) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Pt(1), and two equivalent Ni(1) atoms. In the second Sn site, Sn(2) is bonded in a 10-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pt(1), and two equivalent Ni(1) atoms. is represented by the CIF file [CIF]
