KOIBr2 crystallizes in the orthorhombic Pnnm space group. K(1) is bonded in a 2-coordinate geometry to two equivalent O(1), three equivalent Br(1), and three equivalent Br(2) atoms. O(1) is bonded in a distorted linear geometry to two equivalent K(1), one Br(1), and one Br(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Br(1) atoms. In the second I site, I(2) is bonded in a distorted square co-planar geometry to two equivalent Br(1) and two equivalent Br(2) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 6-coordinate geometry to three equivalent K(1), one O(1), one I(1), and one I(2) atom. In the second Br site, Br(2) is bonded in a 5-coordinate geometry to three equivalent K(1), one O(1), and one I(2) atom.
