Materials Data on Dy2B3O8 by Materials Project
Dy2B3O8 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Dy is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Dy–O bond distances ranging from 2.32–2.43 Å. There are two inequivalent B sites. In the first B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There is two shorter (1.48 Å) and two longer (1.49 Å) B–O bond length. In the second B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.51 Å. There are four inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Dy and two B atoms. In the second O site, O is bonded in a distorted single-bond geometry to two equivalent Dy and one B atom. In the third O site, O is bonded in a distorted single-bond geometry to three equivalent Dy and one B atom. In the fourth O site, O is bonded in a distorted bent 120 degrees geometry to one Dy and two equivalent B atoms.
