Materials Data on P2W2O11 by Materials Project
W2O3(PO4)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share a cornercorner with one WO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of W–O bond distances ranging from 1.73–2.15 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share a cornercorner with one WO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of W–O bond distances ranging from 1.73–2.16 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 WO6 octahedra. The corner-sharing octahedra tilt angles range from 2–40°. There are a spread of P–O bond distances ranging from 1.52–1.55 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four WO6 octahedra. The corner-sharing octahedra tilt angles range from 32–38°. There are a spread of P–O bond distances ranging from 1.51–1.56 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one W6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one W6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one W6+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a linear geometry to one W6+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one W6+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one W6+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one W6+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one W6+ and one P5+ atom.
