Materials Data on KIrO3 by Materials Project
KIrO3 crystallizes in the cubic Pn-3 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are three shorter (2.71 Å) and three longer (2.90 Å) K–O bond lengths. In the second K1+ site, K1+ is bonded in a hexagonal planar geometry to six equivalent O2- atoms. All K–O bond lengths are 2.63 Å. Ir5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Ir–O bond distances ranging from 1.96–2.01 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two K1+ and two equivalent Ir5+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+ and two equivalent Ir5+ atoms.
