(NH4)2H3O6I crystallizes in the triclinic P1 space group. The structure consists of two ammonium molecules inside a H3O6I framework. In the H3O6I framework, there are three inequivalent H sites. In the first H site, H(9) is bonded in a distorted single-bond geometry to one O(1) and one O(4) atom. In the second H site, H(10) is bonded in a distorted single-bond geometry to one O(2) and one O(5) atom. In the third H site, H(11) is bonded in a distorted single-bond geometry to one O(3) and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one H(9) and one I(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one H(10) and one I(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one H(11) and one I(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one H(9) and one I(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one H(10) and one I(1) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one H(11) and one I(1) atom. I(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom.
