Materials Data on Dy3GeO8 by Materials Project

Abstract

Dy3GeO8 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Dy–O bond distances ranging from 2.31–2.46 Å. In the second Dy site, Dy is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Dy–O bond distances ranging from 2.25–2.40 Å. Ge is bonded in a distorted trigonal bipyramidal geometry to five O atoms. There are a spread of Ge–O bond distances ranging from 1.81–1.89 Å. There are five inequivalent O sites. In the first O site, O is bonded in a distorted linear geometry to one Dy and one Ge atom. In the second O site, O is bonded in a trigonal non-coplanar geometry to three Dy atoms. In the third O site, O is bonded to three Dy and one Ge atom to form a mixture of edge and corner-sharing ODy3Ge tetrahedra. In the fourth O site, O is bonded to three Dy and one Ge atom to form a mixture of edge and corner-sharing ODy3Ge tetrahedra. In the fifth O site, O is bonded in a trigonal non-coplanar geometry to three Dy atoms.
