Abstract

Y2W2O9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Y–O bond distances ranging from 2.30–2.67 Å. In the second Y3+ site, Y3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Y–O bond distances ranging from 2.37–2.56 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form distorted corner-sharing WO6 octahedra. There are a spread of W–O bond distances ranging from 1.83–2.20 Å. In the second W6+ site, W6+ is bonded to five O2- atoms to form corner-sharing WO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 45–55°. There are a spread of W–O bond distances ranging from 1.84–1.94 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Y3+ and one W6+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Y3+ and two W6+ atoms. In the third O2- site, O2-more »« less
