Materials Data on Zn2SnWO6 by Materials Project
WZn2SnO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent SnO6 octahedra and corners with eight equivalent ZnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–64°. There are a spread of W–O bond distances ranging from 1.92–2.05 Å. Zn2+ is bonded to four O2- atoms to form distorted ZnO4 tetrahedra that share corners with four equivalent WO6 octahedra, corners with four equivalent SnO6 octahedra, and corners with two equivalent ZnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–92°. There are a spread of Zn–O bond distances ranging from 1.97–2.09 Å. Sn2+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent WO6 octahedra and corners with eight equivalent ZnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–64°. There are a spread of Sn–O bond distances ranging from 2.36–2.65 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one W6+, one Zn2+, and one Sn2+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one W6+, one Zn2+, and one Sn2+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one W6+, two equivalent Zn2+, and one Sn2+ atom.
