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.
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. There are a spread of K(1)-O(1) bond distances ranging from 2.56-3.18 Å. In the second K site, K(2) is bonded in a 3-coordinate geometry to four equivalent O(1) atoms. There are a spread of K(2)-O(1) bond distances ranging from 2.61-3.24 Å. O(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent K(2) atoms.
