The compound described by NdPtGe2 crystallizes in the orthorhombic Immm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(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 Nd site, Nd(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 Nd(1), three equivalent Nd(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 Nd(1) and two equivalent Pt(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(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 Nd(1), three equivalent Nd(2), three equivalent Pt(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
