KIO3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.80–3.47 Å. In the second K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.34 Å. In the third K1+ site, K1+ is bonded in a 12-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.96–3.44 Å. In the fourth K1+ site, K1+ is bonded in a 6-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.31 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.70 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.77 Å) O–I bond lengths. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.76 Å) O–I bond lengths. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.70 Å) O–I bond lengths. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.80 Å) O–I bond lengths. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.70 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one I5+ atom. The O–I bond length is 1.84 Å. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to four K1+ and one I5+ atom. The O–I bond length is 1.84 Å. There are four inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 6-coordinate geometry to five O2- atoms. In the second I5+ site, I5+ is bonded in a 6-coordinate geometry to four O2- atoms. In the third I5+ site, I5+ is bonded in a 6-coordinate geometry to five O2- atoms. In the fourth I5+ site, I5+ is bonded in a 6-coordinate geometry to four O2- atoms.
