The material structure described by Rh2Ga9 crystallizes in the monoclinic Pc space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to one Ga(1), one Ga(3), one Ga(4), one Ga(5), one Ga(6), one Ga(7), one Ga(8), and two equivalent Ga(2) atoms. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to one Ga(1), one Ga(3), one Ga(4), one Ga(5), one Ga(6), one Ga(7), one Ga(8), and two equivalent Ga(9) atoms. There are nine inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 150 degrees geometry to one Rh(1) and one Rh(2) atom. In the second Ga site, Ga(2) is bonded in a 2-coordinate geometry to two equivalent Rh(1) atoms. In the third Ga site, Ga(3) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom. In the fourth Ga site, Ga(4) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom. In the fifth Ga site, Ga(5) is bonded in a distorted bent 120 degrees geometry to one Rh(1) and one Rh(2) atom. In the sixth Ga site, Ga(6) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom. In the seventh Ga site, Ga(7) is bonded in a distorted bent 150 degrees geometry to one Rh(1) and one Rh(2) atom. In the eighth Ga site, Ga(8) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom. In the ninth Ga site, Ga(9) is bonded in a 2-coordinate geometry to two equivalent Rh(2) atoms. is represented by the CIF card [CIF]
