The structure described by Nd2RhGe3 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 Rh(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms to form NdGe10Rh2 cuboctahedra that share edges with four equivalent Nd(1)Ge10Rh2 cuboctahedra, edges with eight equivalent Nd(2)Ge8Rh4 cuboctahedra, faces with four equivalent Nd(1)Ge10Rh2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Rh4 cuboctahedra. In the second Nd site, Nd(2) is bonded to four equivalent Rh(1), two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms to form NdGe8Rh4 cuboctahedra that share edges with four equivalent Nd(2)Ge8Rh4 cuboctahedra, edges with eight equivalent Nd(1)Ge10Rh2 cuboctahedra, faces with four equivalent Nd(1)Ge10Rh2 cuboctahedra, and faces with four equivalent Nd(2)Ge8Rh4 cuboctahedra. Rh(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 Rh(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 Rh(1), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
