KI(OF)2 crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to four O2- and five F1- atoms. There are a spread of K–O bond distances ranging from 2.80–3.36 Å. There are a spread of K–F bond distances ranging from 2.70–3.10 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.81 Å. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.80 Å. I5+ is bonded in a distorted rectangular see-saw-like geometry to two O2- and two F1- atoms. There are one shorter (2.04 Å) and one longer (2.07 Å) I–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to three equivalent K1+ and one I5+ atom. In the second F1- site, F1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom.
