Title: Materials Data on Dy2Ge2O7 by Materials Project

Abstract

Dy2Ge2O7 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to six O2- atoms to form distorted DyO6 pentagonal pyramids that share corners with six equivalent GeO4 tetrahedra and edges with three equivalent DyO6 pentagonal pyramids. There are a spread of Dy–O bond distances ranging from 2.25–2.31 Å. In the second Dy3+ site, Dy3+ is bonded to six O2- atoms to form distorted DyO6 pentagonal pyramids that share corners with six equivalent GeO4 tetrahedra and edges with three equivalent DyO6 pentagonal pyramids. There are a spread of Dy–O bond distances ranging from 2.26–2.34 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with six DyO6 pentagonal pyramids and a cornercorner with one GeO4 tetrahedra. All Ge–O bond lengths are 1.77 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Dy3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Dy3+ and one Ge4+ atom. In the third O2- site, O2- is bonded inmore » a distorted trigonal planar geometry to two Dy3+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent Ge4+ atoms.« less
