The structure described by KPO4 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and three equivalent O(4) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent K(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent K(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
