Ce7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Ce site, Ce(3) is bonded in a distorted water-like geometry to four equivalent Rh(1) atoms. In the third Ce site, Ce(2) is bonded in a 3-coordinate geometry to four equivalent Rh(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to one Ce(1), four equivalent Ce(2), and four equivalent Ce(3) atoms.
Ce7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. All Ce(1)-Rh(1) bond lengths are 2.97 Å. In the second Ce site, Ce(3) is bonded in a distorted water-like geometry to four equivalent Rh(1) atoms. There are two shorter (2.83 Å) and two longer (3.46 Å) Ce(3)-Rh(1) bond lengths. In the third Ce site, Ce(2) is bonded in a 3-coordinate geometry to four equivalent Rh(1) atoms. There are a spread of Ce(2)-Rh(1) bond distances ranging from 2.82-3.48 Å. Rh(1) is bonded in a 9-coordinate geometry to one Ce(1), four equivalent Ce(2), and four equivalent Ce(3) atoms.
