The structure described by KIO3 crystallizes in the trigonal R3c space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded in a 1-coordinate geometry to two 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 card [CIF]
