The structure described by KAsOF4 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent F(1), two equivalent F(2), two equivalent F(3), and two equivalent F(4) atoms. As(1) is bonded to two equivalent O(1), one F(1), one F(2), one F(3), and one F(4) atom to form edge-sharing AsO2F4 octahedra. O(1) is bonded in a distorted L-shaped geometry to one K(1) and two equivalent As(1) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one As(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and one As(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one As(1) atom. In the fourth F site, F(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one As(1) atom. is represented by the CIF card [CIF]
