The structure described by RbFeO2 crystallizes in the orthorhombic Pna2_1 space group. Rb(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Fe(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing FeO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to three equivalent Rb(1) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to three equivalent Rb(1) and two equivalent Fe(1) atoms. is represented by the CIF card [CIF]
