HIO3 is Indium-like structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of four HIO3 clusters. H(1) is bonded in a single-bond geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one I(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one H(1) and one I(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one H(1) and one I(1) atom. I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom.
