Nd2PtGe3 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to two equivalent Pt(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms to form NdGe10Pt2 cuboctahedra that share edges with four equivalent Nd(1)Ge10Pt2 cuboctahedra, edges with eight equivalent Nd(2)Ge8Pt4 cuboctahedra, faces with four equivalent Nd(1)Ge10Pt2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Pt4 cuboctahedra. In the second Nd site, Nd(2) is bonded to four equivalent Pt(1), two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms to form NdGe8Pt4 cuboctahedra that share edges with four equivalent Nd(2)Ge8Pt4 cuboctahedra, edges with eight equivalent Nd(1)Ge10Pt2 cuboctahedra, faces with four equivalent Nd(1)Ge10Pt2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Pt4 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Ge(3), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Ge(2), and two equivalent Ge(3) 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(1) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Pt(1), and two equivalent Ge(1) atoms.
