Materials Data on KSbO3 by Materials Project

KSbO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a distorted pentagonal planar geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.60–2.99 Å. Sb5+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 1.89–2.42 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to three equivalent K1+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one K1+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one K1+, two equivalent Sb5+, and one O2- atom. The O–O bond length is 1.46 Å.
