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.
CeRh2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to twelve equivalent Rh atoms. All Ce–Rh bond lengths are 3.15 Å. Rh is bonded to six equivalent Ce and six equivalent Rh atoms to form a mixture of edge, face, and corner-sharing RhCe6Rh6 cuboctahedra. All Rh–Rh bond lengths are 2.68 Å.
CeRh crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 5-coordinate geometry to seven equivalent Rh atoms. There are a spread of Ce–Rh bond distances ranging from 2.83–3.28 Å. Rh is bonded in a 5-coordinate geometry to seven equivalent Ce atoms.
