Materials Data on UGaRh by Materials Project
URhGa crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. U is bonded in a 5-coordinate geometry to five Rh and six equivalent Ga atoms. All U–Rh bond lengths are 2.90 Å. There are two shorter (3.11 Å) and four longer (3.25 Å) U–Ga bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to three equivalent U and six equivalent Ga atoms. All Rh–Ga bond lengths are 2.63 Å. In the second Rh site, Rh is bonded in a 9-coordinate geometry to six equivalent U and three equivalent Ga atoms. All Rh–Ga bond lengths are 2.68 Å. Ga is bonded in a 12-coordinate geometry to six equivalent U and four Rh atoms.
