The material described by KFeO2 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Fe(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of edge and corner-sharing FeO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent K(1) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent K(1) and two equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
