RhGa3 crystallizes in the tetragonal P4_2/mnm space group. Rh(1) is bonded in a 8-coordinate geometry to two equivalent Ga(1) and six equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to two equivalent Rh(1) atoms. In the second Ga site, Ga(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms.
RhGa3 crystallizes in the tetragonal P4_2/mnm space group. Rh(1) is bonded in a 8-coordinate geometry to two equivalent Ga(1) and six equivalent Ga(2) atoms. Both Rh(1)-Ga(1) bond lengths are 2.44 Å. There are two shorter (2.44 Å) and four longer (2.57 Å) Rh(1)-Ga(2) bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to two equivalent Rh(1) atoms. In the second Ga site, Ga(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms.
