IrCoGa2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two IrCoGa2 ribbons oriented in the (1, 0, 0) direction. Ir is bonded in a linear geometry to two equivalent Ga atoms. Both Ir–Ga bond lengths are 2.38 Å. Co is bonded in a linear geometry to two equivalent Ga atoms. Both Co–Ga bond lengths are 2.40 Å. Ga is bonded in a linear geometry to one Ir and one Co atom.
IrCoGa2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ir is bonded in a distorted body-centered cubic geometry to six equivalent Co and eight equivalent Ga atoms. All Ir–Co bond lengths are 2.99 Å. All Ir–Ga bond lengths are 2.59 Å. Co is bonded in a distorted body-centered cubic geometry to six equivalent Ir and eight equivalent Ga atoms. All Co–Ga bond lengths are 2.59 Å. Ga is bonded in a body-centered cubic geometry to four equivalent Ir and four equivalent Co atoms.
