Abstract

K2O crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.06 Å. In the second K1+ site, K1+ is bonded to four O2- atoms to form a mixture of distorted corner and edge-sharing KO4 tetrahedra. There are a spread of K–O bond distances ranging from 2.63–2.89 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to six K1+ atoms. In the second O2- site, O2- is bonded in a 9-coordinate geometry to nine K1+ atoms. In the third O2- site, O2- is bonded in a 9-coordinate geometry to nine K1+ atoms.
