Materials Data on K2O by Materials Project
K2O crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one K2O sheet oriented in the (0, 0, 1) direction. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All K–O bond lengths are 2.71 Å. In the second K1+ site, K1+ is bonded in a 3-coordinate geometry to four equivalent O2- atoms. There are three shorter (2.67 Å) and one longer (3.21 Å) K–O bond lengths. O2- is bonded in a 7-coordinate geometry to seven K1+ atoms.
