The crystal structure described by K(O3I)2 crystallizes in the orthorhombic Fdd2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(5), one O(8), two equivalent O(6), and two equivalent O(9) atoms. In the second K site, K(2) is bonded in a body-centered cubic geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. There are nine inequivalent O sites. In the first O site, O(7) is bonded in a single-bond geometry to one I(3) atom. In the second O site, O(8) is bonded in a 3-coordinate geometry to one K(1), one I(1), and one I(3) atom. In the third O site, O(1) is bonded in a 1-coordinate geometry to one K(1) and one I(1) atom.

In the fifth O site, O(2) is bonded in a 4-coordinate geometry to one K(1), one K(2), one I(1), and one I(2) atom. In the sixth O site, O(6) is bonded in a 1-coordinate geometry to two equivalent K(1) and one I(2) atom. In the seventh O site, O(3) is bonded in a distorted single-bond geometry to one K(2) and one I(1) atom. In the eighth O site, O(4) is bonded in a 1-coordinate geometry to one K(2) and one I(2) atom. In the ninth O site, O(5) is bonded in a 4-coordinate geometry to one K(1), one K(2), one I(1), and one I(2) atom. There are three inequivalent I sites. In the first I site, I(3) is bonded in a 3-coordinate geometry to one O(7), one O(8), and one O(9) atom. In the second I site, I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(8) atom.
