CeRh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ce is bonded to twelve equivalent Rh atoms to form a mixture of corner and face-sharing CeRh12 cuboctahedra. All Ce–Rh bond lengths are 2.88 Å. Rh is bonded in a distorted square co-planar geometry to four equivalent Ce atoms.
Ce5Rh4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Ce sites. In the first Ce site, Ce is bonded in a 7-coordinate geometry to seven Rh atoms. There are a spread of Ce–Rh bond distances ranging from 2.84–3.37 Å. In the second Ce site, Ce is bonded in a 6-coordinate geometry to six Rh atoms. There are a spread of Ce–Rh bond distances ranging from 2.80–3.04 Å. In the third Ce site, Ce is bonded to six Rh atoms to form distorted corner-sharing CeRh6 octahedra. The corner-sharing octahedra tilt angles range from 47–52°.
