The material structure described by K2O crystallizes in the monoclinic P2_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. In the second K site, K(2) is bonded in a 3-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent K(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
