NdRhZn crystallizes in the orthorhombic Pnma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to two equivalent Rh(2) and three equivalent Rh(1) atoms. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to one Rh(1) and four equivalent Rh(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to one Nd(2), three equivalent Nd(1), two equivalent Zn(2), and three equivalent Zn(1) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Zn(1), and two equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 4-coordinate geometry to one Rh(2) and three equivalent Rh(1) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to two equivalent Rh(1) and two equivalent Rh(2) atoms.
NdRhZn crystallizes in the orthorhombic Pnma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to two equivalent Rh(2) and three equivalent Rh(1) atoms. Both Nd(1)-Rh(2) bond lengths are 2.94 Å. There are two shorter (2.95 Å) and one longer (3.09 Å) Nd(1)-Rh(1) bond length. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to one Rh(1) and four equivalent Rh(2) atoms. The Nd(2)-Rh(1) bond length is 2.85 Å. All Nd(2)-Rh(2) bond lengths are 2.97 Å. There are two inequivalent Rh sites.
