description: W2O3(PO4)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four 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 1°. There are a spread of W–O bond distances ranging from 1.73–2.16 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 1°. There are a spread of W–O bond distances ranging from 1.73–2.18 Å. In the third 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 26°. There are a spread of W–O bond distances ranging from 1.73–2.13 Å. In the fourth W6+ site, W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share a cornercorner with one WO6 octahedra and corners with four PO4 tetrahedra.

In the third 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 23–41°. There are a spread of P–O bond distances ranging from 1.51–1.56 Å. In the fourth 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 5–42°. There is one shorter (1.52 Å) and three longer (1.55 Å) P–O bond length. There are twenty-two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one W6+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one W6+ and one P5+ atom.
