The Materials Project

KO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of K–O bond distances ranging from 2.69–2.91 Å. There are two inequivalent O sites. In the first O site, O is bonded in a 5-coordinate geometry to four equivalent K and one O atom. The O–O bond length is 1.36 Å. In the second O site, O is bonded to five equivalent K and one O atom to form a mixture of distorted corner and edge-sharing OK5O octahedra. The corner-sharing octahedra tilt angles range from 18–83°.
