Materials Data on K3Nb(SO4)4 by Materials Project
K3Nb(SO4)4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.81–3.18 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.69–3.31 Å. Nb5+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nb–O bond distances ranging from 2.09–2.18 Å. There are three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.56 Å. In the second S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.44–1.55 Å. In the third S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.55 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one K1+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Nb5+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a water-like geometry to one Nb5+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Nb5+, and one S6+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Nb5+, and one S6+ atom. In the ninth O2- site, O2- is bonded in a water-like geometry to one Nb5+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Nb5+, and one S6+ atom.
