Abstract

K2O crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a linear geometry to two equivalent O2- atoms. Both K–O bond lengths are 2.56 Å. In the second K1+ site, K1+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All K–O bond lengths are 2.86 Å. O2- is bonded to six K1+ atoms to form a mixture of edge and corner-sharing OK6 octahedra. The corner-sharing octahedral tilt angles are 0°.
