Title: Materials Data on Y2W2O9 by Materials Project

Abstract

Y2W2O9 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.20–2.84 Å. In the second Y3+ site, Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.21–2.85 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 28–38°. There are a spread of W–O bond distances ranging from 1.83–2.16 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 27–37°. There are a spread of W–O bond distances ranging from 1.83–2.16 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Y3+ and two equivalent W6+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Y3+ and two equivalent W6+ atoms.more » In the third O2- site, O2- is bonded to four Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent W6+ atoms. In the fifth O2- site, O2- is bonded to four Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent W6+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Y3+ and one W6+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Y3+ and one W6+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms.« less
