Abstract

Na4W4O15 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Na sites. In the first Na site, Na is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Na–O bond distances ranging from 2.37–2.82 Å. In the second Na site, Na is bonded to six O atoms to form NaO6 octahedra that share a cornercorner with one NaO6 octahedra, corners with three equivalent WO6 octahedra, and an edgeedge with one NaO6 octahedra. The corner-sharing octahedra tilt angles range from 0–62°. There are a spread of Na–O bond distances ranging from 2.28–2.68 Å. There are two inequivalent W sites. In the first W site, W is bonded in a 6-coordinate geometry to six O atoms. There are a spread of W–O bond distances ranging from 1.79–2.28 Å. In the second W site, W is bonded to six O atoms to form distorted WO6 octahedra that share corners with three equivalent NaO6 octahedra and an edgeedge with one WO6 octahedra. The corner-sharing octahedra tilt angles range from 49–62°. There are a spread of W–O bond distances ranging from 1.80–2.15 Å. There are eight inequivalent O sites. In the first O site,more »« less
