KSeO2F crystallizes in the monoclinic P2_1/m space group. K(1) is bonded to six equivalent O(1) and one F(1) atom to form distorted edge-sharing KO6F pentagonal bipyramids. Se(1) is bonded in a trigonal non-coplanar geometry to two equivalent O(1) and one F(1) atom. O(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Se(1) atom. F(1) is bonded in a bent 120 degrees geometry to one K(1) and one Se(1) atom.
KSeO2F crystallizes in the monoclinic P2_1/m space group. K(1) is bonded to six equivalent O(1) and one F(1) atom to form distorted edge-sharing KO6F pentagonal bipyramids. There are four shorter (2.88 Å) and two longer (2.95 Å) K(1)-O(1) bond lengths. The K(1)-F(1) bond length is 2.91 Å. Se(1) is bonded in a trigonal non-coplanar geometry to two equivalent O(1) and one F(1) atom. Both Se(1)-O(1) bond lengths are 1.67 Å. The Se(1)-F(1) bond length is 1.94 Å. O(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Se(1) atom. F(1) is bonded in a bent 120 degrees geometry to one K(1) and one Se(1) atom.
