URhAl crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 5-coordinate geometry to one Rh(1) and four equivalent Rh(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Al(1) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Al(1) atoms. Al(1) is bonded to two equivalent Rh(1) and two equivalent Rh(2) atoms to form a mixture of distorted edge and corner-sharing AlRh4 tetrahedra.
URhAl crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 5-coordinate geometry to one Rh(1) and four equivalent Rh(2) atoms. The U(1)-Rh(1) bond length is 2.90 Å. All U(1)-Rh(2) bond lengths are 2.92 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Al(1) atoms.
