KH2(IO3)3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.84–2.99 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.83–2.91 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.70 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.05 Å) and one longer (1.50 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.05 Å) and one longer (1.52 Å) H–O bond length. There are eighteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one I5+ atom. The O–I bond length is 1.85 Å. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one I5+ atom. The O–I bond length is 1.94 Å.

In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two I5+ atoms. There are one shorter (1.88 Å) and one longer (2.56 Å) O–I bond lengths. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two I5+ atoms. There are one shorter (1.85 Å) and one longer (2.62 Å) O–I bond lengths. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.85 Å) and one longer (2.48 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.82 Å) and one longer (2.68 Å) O–I bond lengths. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.83 Å) and one longer (2.55 Å) O–I bond lengths. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.50 Å) O–I bond lengths. In the thirteenth O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one I5+ atom. The O–I bond length is 1.93 Å. In the fourteenth O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one I5+ atom. The O–I bond length is 1.92 Å. In the fifteenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one H1+, and one I5+ atom. The O–I bond length is 1.85 Å. In the sixteenth O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one I5+ atom. The O–I bond length is 1.94 Å.
