The compound described by Ir2Ga9 crystallizes in the monoclinic Pc space group. There are two inequivalent Ir sites. In the first Ir site, Ir(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 Ir site, Ir(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 Ir(1) and one Ir(2) atom. In the second Ga site, Ga(2) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. In the third Ga site, Ga(3) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom. In the fourth Ga site, Ga(4) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom. In the fifth Ga site, Ga(5) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom. In the sixth Ga site, Ga(6) is bonded in a distorted bent 120 degrees geometry to one Ir(1) and one Ir(2) atom. In the seventh Ga site, Ga(7) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom. In the eighth Ga site, Ga(8) is bonded in a distorted bent 150 degrees geometry to one Ir(1) and one Ir(2) atom. In the ninth Ga site, Ga(9) is bonded in a 2-coordinate geometry to two equivalent Ir(2) atoms. is represented by the CIF file [CIF]
