Materials Data on Dy5B3O13 by Materials Project
Dy5B3O13 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 9-coordinate geometry to nine O atoms. There are six shorter (2.34 Å) and three longer (2.64 Å) Dy–O bond lengths. 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 2.20–2.52 Å. B is bonded in a tetrahedral geometry to four O atoms. There are a spread of B–O bond distances ranging from 1.46–1.49 Å. There are four inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to three equivalent Dy atoms. In the second O site, O is bonded in a 4-coordinate geometry to three Dy and one B atom. In the third O site, O is bonded in a 1-coordinate geometry to three Dy and one B atom. In the fourth O site, O is bonded in a distorted single-bond geometry to three Dy and one B atom.
