The material structure described by CePtGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 14-coordinate geometry to four equivalent Pt(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Ce site, Ce(2) is bonded in a 14-coordinate geometry to six equivalent Pt(1), two equivalent Ge(2), and six equivalent Ge(3) atoms. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), one Ge(1), one Ge(2), and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 7-coordinate geometry to four equivalent Ce(1), two equivalent Pt(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pt(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Ce(1), three equivalent Ce(2), three equivalent Pt(1), and one Ge(3) atom. is represented by the CIF file [CIF]
