The material structure described by CaPtGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ca sites. In the first Ca site, Ca(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 Ca site, Ca(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 Ca(1), three equivalent Ca(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 2-coordinate geometry to four equivalent Ca(1) and two equivalent Pt(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ca(2), four equivalent Ca(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 Ca(1), three equivalent Ca(2), three equivalent Pt(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
