Materials Data on K2PSO8 by Materials Project
K2PSO8 crystallizes in the triclinic P-1 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 2.76–3.03 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 2.74–3.07 Å. P is bonded in a tetrahedral geometry to four O atoms. There is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. 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 three K and one P 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 P 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 single-bond geometry to two K and one P atom. In the sixth O site, O is bonded in a 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 two K and one P atom. In the eighth O site, O is bonded in a distorted single-bond geometry to two K and one S atom.
