Materials Data on KSO3 by Materials Project

Abstract

KSO3 crystallizes in the trigonal P321 space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded to eight O atoms to form corner-sharing KO8 hexagonal bipyramids. There are a spread of K–O bond distances ranging from 2.79–3.02 Å. In the second K site, K is bonded in a 6-coordinate geometry to six O atoms. There are a spread of K–O bond distances ranging from 2.84–2.97 Å. There are three inequivalent S sites. In the first S site, S is bonded in a trigonal non-coplanar geometry to three equivalent O atoms. All S–O bond lengths are 1.47 Å. In the second S site, S is bonded in a trigonal non-coplanar geometry to three equivalent O atoms. All S–O bond lengths are 1.47 Å. In the third S site, S is bonded in a distorted trigonal non-coplanar geometry to three equivalent O atoms. All S–O bond lengths are 1.47 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two K and one S atom. In the second O site, O is bonded in a distorted single-bond geometry to three K and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to two K and one S atom.
