Materials Data on KSbO3 by Materials Project

Abstract

KSbO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.71–2.95 Å. Sb5+ is bonded to five O2- atoms to form edge-sharing SbO5 square pyramids. There are a spread of Sb–O bond distances ranging from 2.07–2.12 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent K1+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one Sb5+, and one O2- atom. The O–O bond length is 1.48 Å.
