The material structure described by URhGa crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 11-coordinate geometry to one Rh(2), four equivalent Rh(1), and six equivalent Ga(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Ga(1) atoms. In the second Rh site, Rh(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Ga(1) atoms. Ga(1) is bonded in a 12-coordinate geometry to six equivalent U(1), two equivalent Rh(1), two equivalent Rh(2), and two equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
