The material described by CeRh2Si crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Rh(2), six equivalent Rh(1), and four equivalent Si(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1), two equivalent Rh(1), and one Si(1) atom. In the second Rh site, Rh(2) is bonded to four equivalent Ce(1) and four equivalent Si(1) atoms to form a mixture of distorted edge and face-sharing RhCe4Si4 tetrahedra. Si(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Rh(1), and four equivalent Rh(2) atoms. is represented by the CIF file [CIF]
