Materials Data on W2O7 by Materials Project

W2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. W is bonded in a distorted body-centered cubic geometry to eight O atoms. There are six shorter (2.01 Å) and two longer (2.21 Å) W–O bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent W atoms. In the second O site, O is bonded to four equivalent W atoms to form corner-sharing OW4 tetrahedra.

Materials Data on W2O7 by Materials Project

(WO3)4O2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional and consists of eight water molecules and one WO3 framework. In the WO3 framework, W is bonded to six equivalent O atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 37°. All W–O bond lengths are 1.94 Å. O is bonded in a bent 150 degrees geometry to two equivalent W atoms.
