Materials Data on CsSb2PO8 by Materials Project
CsSb2PO8 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.21–3.24 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to eleven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.12–3.70 Å. There are three inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with four SbO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 44–49°. There are a spread of Sb–O bond distances ranging from 1.97–2.08 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra, corners with two PO4 tetrahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Sb–O bond distances ranging from 1.96–2.08 Å. In the third Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra, corners with two PO4 tetrahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Sb–O bond distances ranging from 1.97–2.11 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four SbO6 octahedra. The corner-sharing octahedra tilt angles range from 2–54°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four SbO6 octahedra. The corner-sharing octahedra tilt angles range from 43–50°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+ and two Sb5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb5+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Sb5+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb5+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+ and two equivalent Sb5+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Sb5+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Sb5+ atoms. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Sb5+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+ and two Sb5+ atoms. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to two Cs1+ and two Sb5+ atoms. In the eleventh O2- site, O2- is bonded in a linear geometry to two equivalent Cs1+, one Sb5+, and one P5+ atom.
