Materials Data on KIO2 by Materials Project
KO2I crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K is bonded in a distorted body-centered cubic geometry to eight equivalent O atoms. All K–O bond lengths are 2.98 Å. O is bonded to four equivalent K and two equivalent I atoms to form a mixture of corner, edge, and face-sharing OK4I2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°. Both O–I bond lengths are 2.15 Å. I is bonded in a square co-planar geometry to four equivalent O atoms.
