Materials Data on Na(WO3)2 by Materials Project

Abstract

Na(WO3)2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to twelve equivalent O2- atoms to form NaO12 cuboctahedra that share corners with twelve equivalent NaO12 cuboctahedra and faces with eight equivalent WO6 octahedra. All Na–O bond lengths are 2.76 Å. W+5.50+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent WO6 octahedra and faces with four equivalent NaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All W–O bond lengths are 1.95 Å. O2- is bonded in a distorted square co-planar geometry to two equivalent Na1+ and two equivalent W+5.50+ atoms.
