Sr3(IrSn)4 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Sr is bonded in a 12-coordinate geometry to four equivalent Ir and four equivalent Sn atoms. All Sr–Ir bond lengths are 3.39 Å. All Sr–Sn bond lengths are 3.36 Å. Ir is bonded in a 4-coordinate geometry to three equivalent Sr, three equivalent Ir, and four equivalent Sn atoms. All Ir–Ir bond lengths are 2.88 Å. There are one shorter (2.58 Å) and three longer (2.72 Å) Ir–Sn bond lengths. Sn is bonded in a 7-coordinate geometry to three equivalent Sr and four equivalent Ir atoms.
