K2MnSO4F3 crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 8-coordinate geometry to one O(2), three equivalent O(1), one F(2), and three equivalent F(1) atoms. Mn(1) is bonded to two equivalent O(2), two equivalent F(1), and two equivalent F(2) atoms to form MnO2F4 octahedra that share corners with two equivalent Mn(1)O2F4 octahedra and corners with two equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with two equivalent Mn(1)O2F4 octahedra. The corner-sharing octahedral tilt angles are 51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one S(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Mn(1), and one S(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Mn(1) atom. In the second F site, F(2) is bonded to two equivalent K(1) and two equivalent Mn(1) atoms to form distorted corner-sharing FK2Mn2 tetrahedra.
