Materials Data on Dy2GeO5 by Materials Project
Dy2GeO5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Dy–O bond distances ranging from 2.21–2.70 Å. In the second Dy3+ site, Dy3+ is bonded to six O2- atoms to form distorted DyO6 octahedra that share corners with four equivalent GeO4 tetrahedra and edges with two equivalent DyO6 octahedra. There are a spread of Dy–O bond distances ranging from 2.22–2.34 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four equivalent DyO6 octahedra. The corner-sharing octahedra tilt angles range from 44–69°. There are a spread of Ge–O bond distances ranging from 1.76–1.79 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Dy3+ and one Ge4+ atom. In the second O2- site, O2- is bonded to four Dy3+ atoms to form distorted edge-sharing ODy4 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Dy3+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Dy3+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Dy3+ and one Ge4+ atom.
