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 2.44–2.83 Å. In the second Na1+ site, Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.52–2.63 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 2.59–2.62 Å. W+2.25+ is bonded in a T-shaped geometry to three O2- atoms. There are a spread of W–O bond distances ranging from 1.97–2.06 Å. 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 edge and corner-sharing ONa3W2 trigonal bipyramids. In the second O2- site, O2- is bonded to three Na1+ and two equivalent W+2.25+ atoms to form a mixture of distorted edge, corner, 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 edge, corner, and face-sharing ONa3W2 square pyramids.
