Title: Materials Data on Dy2Cu(WO4)4 by Materials Project

Abstract

Dy2Cu(WO4)4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Dy3+ is bonded to seven O2- atoms to form distorted DyO7 pentagonal bipyramids that share corners with seven WO6 octahedra, an edgeedge with one WO6 octahedra, an edgeedge with one CuO6 octahedra, and an edgeedge with one DyO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 31–57°. There are a spread of Dy–O bond distances ranging from 2.22–2.47 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share a cornercorner with one CuO6 octahedra, corners with two equivalent WO6 octahedra, corners with three equivalent DyO7 pentagonal bipyramids, an edgeedge with one WO6 octahedra, and an edgeedge with one DyO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 11–52°. 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 six O2- atoms to form distorted WO6 octahedra that share corners with three equivalent CuO6 octahedra, corners with four equivalent DyO7 pentagonal bipyramids, and edges with two WO6 octahedra. The corner-sharing octahedra tilt angles range from 50–54°. There are a spreadmore » of W–O bond distances ranging from 1.79–2.14 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with eight WO6 octahedra and edges with two equivalent DyO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 50–54°. There are a spread of Cu–O bond distances ranging from 2.14–2.27 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Dy3+, one W6+, and one Cu2+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Dy3+ and two W6+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Dy3+ and two W6+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent W6+ and one Cu2+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Dy3+, one W6+, and one Cu2+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Dy3+ and one W6+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Dy3+ and one W6+ atom. In the eighth O2- site, O2- is bonded in a distorted linear geometry to two equivalent W6+ atoms.« less
