KSnSO4F crystallizes in the triclinic P-1 space group. K(1) is bonded to one O(2), one O(4), two equivalent O(1), two equivalent O(3), and two equivalent F(1) atoms to form distorted KO6F2 hexagonal bipyramids that share corners with two equivalent S(1)O4 tetrahedra, edges with three equivalent K(1)O6F2 hexagonal bipyramids, and edges with two equivalent S(1)O4 tetrahedra. Sn(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(4), and one F(1) atom. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with two equivalent K(1)O6F2 hexagonal bipyramids and edges with two equivalent K(1)O6F2 hexagonal bipyramids. 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 S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1), one Sn(1), and one S(1) atom.
