The material structure described by KIO4 is Zircon-like structured and crystallizes in the triclinic P-1 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one I(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and one I(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent K(1) and one I(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent K(1) and one I(1) atom. I(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. is represented by the CIF card [CIF]
