Materials Data on Sb2(PO4)3 by Materials Project

Abstract

Sb2(PO4)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sb–O bond distances ranging from 1.96–2.00 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sb–O bond distances ranging from 2.08–2.19 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 PO4 tetrahedra that share corners with four SbO6 octahedra. The corner-sharing octahedra tilt angles range from 25–46°. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. In the second P+4.67+ site, P+4.67+ 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 36–46°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the third P+4.67+ site, P+4.67+ 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 29–46°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Sb5+ and one P+4.67+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Sb5+ and one P+4.67+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Sb5+ and one P+4.67+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one Sb5+ and one P+4.67+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P+4.67+ atom.
