The crystal structure described by Pr4Fe is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight Pr4Fe clusters. Pr(1) is bonded in a single-bond geometry to one Fe(1) atom. Fe(1) is bonded in a tetrahedral geometry to four equivalent Pr(1) atoms. is represented by the CIF card [CIF]
