The structure described by KO2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to four equivalent O(2) and five equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one O(1) atom. In the second O site, O(1) is bonded to five equivalent K(1) and one O(2) atom to form a mixture of distorted corner and edge-sharing OK5O octahedra. The corner-sharing octahedral tilt angles range from 18-83°. is represented by the CIF card [CIF]
