RhZnGa4 crystallizes in the trigonal R3m space group. Rh(1) is bonded in a 6-coordinate geometry to three equivalent Ga(1) and three equivalent Ga(2) atoms. All Rh(1)-Ga(1) bond lengths are 1.78 Å. All Rh(1)-Ga(2) bond lengths are 3.19 Å. Zn(1) is bonded to one Ga(2) and six equivalent Ga(1) atoms to form distorted corner-sharing ZnGa7 hexagonal pyramids. The Zn(1)-Ga(2) bond length is 3.06 Å. All Zn(1)-Ga(1) bond lengths are 2.79 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to one Rh(1), two equivalent Zn(1), one Ga(2), and two equivalent Ga(1) atoms. The Ga(1)-Ga(2) bond length is 1.52 Å. Both Ga(1)-Ga(1) bond lengths are 0.88 Å. In the second Ga site, Ga(2) is bonded in a 7-coordinate geometry to three equivalent Rh(1), one Zn(1), and three equivalent Ga(1) atoms.
