CeRhIn crystallizes in the hexagonal P-6 space group. Ce(1) is bonded in a 11-coordinate geometry to one Rh(2); four Rh(1,1); and six equivalent In(1) atoms. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent In(1) atoms. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent In(1) atoms. In the third Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Ce(1); two Rh(1,1); and two equivalent Rh(2) atoms.
CeRhIn crystallizes in the hexagonal P-6 space group. Ce(1) is bonded in a 11-coordinate geometry to one Rh(2); four Rh(1,1); and six equivalent In(1) atoms. The Ce(1)-Rh(2) bond length is 3.13 Å. All Ce(1)-Rh(1,1) bond lengths are 3.05 Å. There are two shorter (3.27 Å) and four longer (3.39 Å) Ce(1)-In(1) bond lengths. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent In(1) atoms. All Rh(1)-In(1) bond lengths are 2.90 Å. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent In(1) atoms. All Rh(1)-In(1) bond lengths are 2.90 Å. In the third Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent In(1) atoms. All Rh(2)-In(1) bond lengths are 2.76 Å.
