Materials Data on K(IrO2)4 by Materials Project
K(IrO2)4 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All K–O bond lengths are 3.01 Å. Ir+3.75+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Ir–O bond distances ranging from 1.97–2.08 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Ir+3.75+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent K1+ and three equivalent Ir+3.75+ atoms.
