RbFeO2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Fe(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Rb(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb3Fe2 trigonal bipyramids.
RbFeO2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are two shorter (2.87 Å) and four longer (3.04 Å) Rb(1)-O(1) bond lengths. Fe(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (1.87 Å) and two longer (1.88 Å) Fe(1)-O(1) bond lengths. O(1) is bonded to three equivalent Rb(1) and two equivalent Fe(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb3Fe2 trigonal bipyramids.
