Title: Materials Data on Mg3WO4 by Materials Project

Abstract

Mg3WO4 is Caswellsilverite-like structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent MgO6 octahedra, edges with four equivalent WO6 octahedra, and edges with eight equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Mg–O bond lengths are 2.22 Å. W2+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent WO6 octahedra and edges with twelve equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All W–O bond lengths are 2.22 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Mg2+ and two equivalent W2+ atoms to form OMg4W2 octahedra that share corners with six equivalent OMg4W2 octahedra and edges with twelve OMg6 octahedra. The corner-sharing octahedral tilt angles are 0°. All O–Mg bond lengths are 2.22 Å. In the second O2- site, O2- is bonded to six equivalent Mg2+ atoms to form OMg6 octahedra that share corners with six equivalent OMg6 octahedra and edges with twelve OMg4W2 octahedra. The corner-sharing octahedral tilt angles are 0°.
