KO4F crystallizes in the orthorhombic Pbca space group. K(1) is bonded in a 2-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent F(1) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a trigonal planar geometry to two equivalent K(1) and one O(3) atom. In the second O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one O(2) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to one K(1) and one O(1) atom. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to two equivalent K(1) and one O(4) atom. F(1) is bonded in a bent 120 degrees geometry to two equivalent K(1) atoms.
