Ce3Rh2Ge2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to four equivalent Rh(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), one Ge(2), and two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 12-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and four equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1), four equivalent Ce(2), and two equivalent Rh(1) atoms.
