The material structure described by IrGa3 crystallizes in the tetragonal P4_2/mnm space group. Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ga(1) and six equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to two equivalent Ir(1) atoms. In the second Ga site, Ga(2) is bonded in a 3-coordinate geometry to three equivalent Ir(1) atoms. is represented by the CIF file [CIF]
