Materials Data on Dy2WO6 by Materials Project
Dy2WO6 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Dy–O bond distances ranging from 2.27–2.57 Å. In the second Dy3+ site, Dy3+ is bonded to seven O2- atoms to form distorted DyO7 pentagonal bipyramids that share corners with three equivalent WO6 octahedra, edges with two equivalent WO6 octahedra, and an edgeedge with one DyO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 43–55°. There are a spread of Dy–O bond distances ranging from 2.25–2.43 Å. In the third Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Dy–O bond distances ranging from 2.33–2.47 Å. W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share corners with three equivalent DyO7 pentagonal bipyramids and edges with two equivalent DyO7 pentagonal bipyramids. There are a spread of W–O bond distances ranging from 1.88–2.09 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to three Dy3+ and one W6+ atom to form a mixture of edge and corner-sharing ODy3W tetrahedra. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Dy3+ and one W6+ atom. In the third O2- site, O2- is bonded to three Dy3+ and one W6+ atom to form distorted corner-sharing ODy3W tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Dy3+ and one W6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Dy3+ and one W6+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Dy3+ and one W6+ atom.
