The material described by K2WO4 crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. W(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one W(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one W(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one W(1) atom. is represented by the CIF card [CIF]
