Materials Data on Ba3Tm(BO2)9 by Materials Project
Abstract
Ba3Tm(BO2)9 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.75–3.02 Å. In the second Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.75 Å) and three longer (2.91 Å) Ba–O bond lengths. Tm3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Tm–O bond lengths are 2.25 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.33 Å) and two longer (1.41 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.33–1.42 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one B3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry tomore »
