The crystal structure described by Ir3Ga5 crystallizes in the tetragonal P-4n2 space group. There are four inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ga(1), two equivalent Ga(3), and four equivalent Ga(2) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to two equivalent Ga(2), two equivalent Ga(3), and four equivalent Ga(1) atoms. In the third Ir site, Ir(3) is bonded in a 6-coordinate geometry to two equivalent Ga(3) and four equivalent Ga(2) atoms. In the fourth Ir site, Ir(4) is bonded in a 8-coordinate geometry to four equivalent Ga(1) and four equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to one Ir(1), one Ir(4), and two equivalent Ir(2) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to one Ir(2), one Ir(3), one Ir(4), and two equivalent Ir(1) atoms. In the third Ga site, Ga(3) is bonded in a 5-coordinate geometry to one Ir(3), two equivalent Ir(1), and two equivalent Ir(2) atoms. is represented by the CIF card [CIF]
