The structure described by K2PO3F crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to two equivalent O(1), four equivalent O(2), and one F(1) atom. In the second K site, K(2) is bonded in a 8-coordinate geometry to three equivalent O(1), four equivalent O(2), and one F(1) atom. P(1) is bonded in a tetrahedral geometry to one O(1), two equivalent O(2), and one F(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1), three equivalent K(2), and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent K(2), and one P(1) atom. F(1) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one P(1) atom. is represented by the CIF file [CIF]
