The structure described by Rb2FeO4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(1), and four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 10-coordinate geometry to one O(1), three equivalent O(3), and six equivalent O(2) atoms. Fe(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(2), three equivalent Rb(1), and one Fe(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), three equivalent Rb(2), and one Fe(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Rb(1), three equivalent Rb(2), and one Fe(1) atom. is represented by the CIF file [CIF]
