Ce3Rh3Si2 is gamma CuTi-derived structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 9-coordinate geometry to two equivalent Rh(1), three equivalent Rh(2), and four equivalent Si(1) atoms. In the second Ce site, Ce(2) is bonded in a 9-coordinate geometry to two equivalent Rh(2), four equivalent Rh(1), and three equivalent Si(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to one Ce(1), four equivalent Ce(2), and three equivalent Si(1) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1), four equivalent Ce(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), one Rh(2), and three equivalent Rh(1) atoms.
