Materials Data on Na3(W2O3)2 by Materials Project
Na3(W2O3)2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.41–2.71 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.44–2.67 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.36–2.61 Å. W+2.25+ is bonded in a T-shaped geometry to three O2- atoms. There are two shorter (2.02 Å) and one longer (2.03 Å) W–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three Na1+ and two equivalent W+2.25+ atoms to form a mixture of distorted corner and edge-sharing ONa3W2 square pyramids. In the second O2- site, O2- is bonded to three Na1+ and two equivalent W+2.25+ atoms to form a mixture of distorted corner, edge, and face-sharing ONa3W2 square pyramids. In the third O2- site, O2- is bonded to three Na1+ and two equivalent W+2.25+ atoms to form a mixture of corner, edge, and face-sharing ONa3W2 trigonal bipyramids.
