The crystal structure described by IrGa2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to two equivalent Ga(1), two equivalent Ga(3), two equivalent Ga(4), and three equivalent Ga(2) atoms. In the second Ir site, Ir(2) is bonded in a 9-coordinate geometry to one Ga(4), two equivalent Ga(2), two equivalent Ga(3), and four equivalent Ga(1) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), one Ga(1), two equivalent Ga(2), and two equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to one Ir(2), three equivalent Ir(1), and two equivalent Ga(1) atoms. In the third Ga site, Ga(3) is bonded in a 7-coordinate geometry to two equivalent Ir(2), four equivalent Ir(1), and one Ga(4) atom. In the fourth Ga site, Ga(4) is bonded in a 10-coordinate geometry to one Ir(2), four equivalent Ir(1), one Ga(3), and four equivalent Ga(1) atoms. is represented by the CIF file [CIF]
