The structure described by Rb5FeO4 crystallizes in the orthorhombic Pmn2_1 space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Rb site, Rb(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. In the third Rb site, Rb(3) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. Fe(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and one Fe(1) atom. In the second O site, O(2) is bonded in a 8-coordinate geometry to one Rb(3), two equivalent Rb(2), four equivalent Rb(1), and one Fe(1) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to one Rb(3), two equivalent Rb(1), two equivalent Rb(2), and one Fe(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
