The structure described by Ce4Rh4Si3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 11-coordinate geometry to two equivalent Rh(1), five equivalent Rh(2), one Si(2), and three equivalent Si(1) atoms. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to one Rh(2), four equivalent Rh(1), two equivalent Si(1), and three equivalent Si(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to one Ce(2), five equivalent Ce(1), and three equivalent Si(1) atoms. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), one Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), one Rh(1), and three equivalent Rh(2) atoms. In the second Si site, Si(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
