The structure described by K2MnOF5 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to two equivalent O(1), one F(3), two equivalent F(1), and four equivalent F(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent O(1), one F(3), two equivalent F(2), and four equivalent F(1) atoms. Mn(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 16°. O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1) and two equivalent K(2) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one Mn(1) atom. In the third F site, F(3) is bonded in a 2-coordinate geometry to one K(1), one K(2), and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
