The material described by K3VO4 crystallizes in the cubic P2_13 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to one O(2) and six equivalent O(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the third K site, K(3) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. V(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one K(3), two equivalent K(1), two equivalent K(2), and one V(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one K(1), three equivalent K(3), and one V(1) atom. is represented by the CIF file [CIF]
