The structure described by Sr3(IrSn)4 crystallizes in the cubic I-43m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent Ir(1) and eight equivalent Sn(1) atoms. Ir(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Ir(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 7-coordinate geometry to six equivalent Sr(1) and four equivalent Ir(1) atoms. is represented by the CIF file [CIF]
