The compound described by PrPtGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(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 Pr site, Pr(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 Pr(1), three equivalent Pr(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 Pr(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 Pr(2), four equivalent Pr(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 Pr(1), three equivalent Pr(2), three equivalent Pt(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
