Materials Data on KSO4 by Materials Project

Abstract

KSO4 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of K–O bond distances ranging from 2.83–3.13 Å. In the second K site, K is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of K–O bond distances ranging from 2.79–3.10 Å. There are two inequivalent S sites. In the first S site, S is bonded in a tetrahedral geometry to four O atoms. All S–O bond lengths are 1.49 Å. In the second S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.48–1.50 Å. There are eight 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 two 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. In the fourth O site, O is bonded in a distorted single-bond geometry to two K and one S atom. In the fifth O site, O is bonded in a distorted single-bond geometry to three K and one S atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two K and one S atom. In the seventh O site, O is bonded in a distorted single-bond geometry to three K and one S atom. In the eighth O site, O is bonded in a distorted single-bond geometry to two K and one S atom.
