The compound described by KO2I crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a distorted body-centered cubic geometry to eight equivalent O(1) atoms. O(1) is bonded to four equivalent K(1) and two equivalent I(1) atoms to form a mixture of corner, edge, and face-sharing OK4I2 octahedra. The corner-sharing octahedral tilt angles range from 0-61°. I(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
