KZnO2I3 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), two equivalent I(1), two equivalent I(3), and three equivalent I(2) atoms. Zn(1) is bonded in a trigonal planar geometry to one I(1), one I(2), and one I(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one K(1) and one O(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one K(1) and one O(1) atom. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Zn(1) atom. In the second I site, I(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Zn(1) atom. In the third I site, I(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Zn(1) atom.
