The crystal structure described by Sr4Ir is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight Sr4Ir clusters. Sr(1) is bonded in a single-bond geometry to one Ir(1) atom. Ir(1) is bonded in a tetrahedral geometry to four equivalent Sr(1) atoms. is represented by the CIF file [CIF]
