The material structure described by KIO3 crystallizes in the trigonal R3m space group. K(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one I(1) atom. I(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. is represented by the CIF file [CIF]
