Materials Data on Cs3P3HO9 by Materials Project
Cs3P3HO9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 3-coordinate geometry to two equivalent H1+ and seven O2- atoms. There are one shorter (3.27 Å) and one longer (3.38 Å) Cs–H bond lengths. There are a spread of Cs–O bond distances ranging from 2.97–3.73 Å. In the second Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.12–3.61 Å. In the third Cs1+ site, Cs1+ is bonded in a 7-coordinate geometry to one H1+ and six O2- atoms. The Cs–H bond length is 3.33 Å. There are a spread of Cs–O bond distances ranging from 2.96–3.57 Å. There are three inequivalent P+4.67+ sites. In the first P+4.67+ site, P+4.67+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.65 Å) P–O bond length. In the second P+4.67+ site, P+4.67+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.64 Å) P–O bond length. In the third P+4.67+ site, P+4.67+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.65 Å. H1+ is bonded in a 3-coordinate geometry to three Cs1+ atoms. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+ and two P+4.67+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+ and two P+4.67+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P+4.67+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P+4.67+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P+4.67+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to three Cs1+ and one P+4.67+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P+4.67+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P+4.67+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two P+4.67+ atoms.
