The material structure described by Al(IO3)3 crystallizes in the hexagonal P6_3 space group. Al(1) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Al(1) and one I(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Al(1) and one I(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to 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. is represented by the CIF file [CIF]
