La5Rh4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to one Rh(3), two equivalent Rh(2), and three equivalent Rh(1) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to one Rh(2), two equivalent Rh(3), and four equivalent Rh(1) atoms. In the third La site, La(3) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and two equivalent Rh(3) atoms. There are three inequivalent Rh sites. In the first Rh site, Rh(3) is bonded in a 9-coordinate geometry to two equivalent La(1), two equivalent La(3), four equivalent La(2), and one Rh(2) atom. In the second Rh site, Rh(1) is bonded in a 8-coordinate geometry to one La(3), three equivalent La(1), and four equivalent La(2) atoms. In the third Rh site, Rh(2) is bonded in a 9-coordinate geometry to two equivalent La(2), two equivalent La(3), four equivalent La(1), and one Rh(3) atom.
