LaRhZn crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 11-coordinate geometry to two equivalent Rh(1), three equivalent Rh(2), three equivalent Zn(1), and three equivalent Zn(2) atoms. In the second La site, La(2) is bonded in a 5-coordinate geometry to one Rh(2) and four equivalent Rh(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Zn(2), and two equivalent Zn(1) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to one La(2), three equivalent La(1), two equivalent Zn(1), and three 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 three equivalent La(1), two equivalent Rh(1), and two equivalent Rh(2) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to three equivalent La(1), one Rh(1), and three equivalent Rh(2) atoms.
