The compound described by K6MgO4 crystallizes in the hexagonal P6_3mc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. Mg(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1), three equivalent K(2), and one Mg(1) atom. In the second O site, O(2) is bonded in a 8-coordinate geometry to three equivalent K(2), four equivalent K(1), and one Mg(1) atom. is represented by the CIF file [CIF]
