Materials Data on Na5(WO3)14 by Materials Project
Abstract
Na5(WO3)14 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to twelve O2- atoms to form NaO12 cuboctahedra that share corners with ten NaO12 cuboctahedra and faces with eight WO6 octahedra. There are two shorter (2.72 Å) and ten longer (2.75 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded to twelve O2- atoms to form NaO12 cuboctahedra that share corners with six equivalent NaO12 cuboctahedra and faces with eight WO6 octahedra. There are a spread of Na–O bond distances ranging from 2.72–2.75 Å. In the third Na1+ site, Na1+ is bonded to twelve O2- atoms to form NaO12 cuboctahedra that share corners with seven NaO12 cuboctahedra and faces with eight WO6 octahedra. There are a spread of Na–O bond distances ranging from 2.72–2.76 Å. There are four inequivalent W+5.64+ sites. In the first W+5.64+ site, W+5.64+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six WO6 octahedra and faces with three NaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–3°. There are a spread of W–O bond distances ranging from 1.93–1.96 Å. Inmore »
