Materials Data on BaSrTm4O8 by Materials Project
Abstract
BaSrTm4O8 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.71–2.89 Å. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.61–2.91 Å. There are four inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 51–59°. There are a spread of Tm–O bond distances ranging from 2.21–2.31 Å. In the second Tm3+ site, Tm3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 49–59°. There are a spread of Tm–O bond distances ranging from 2.24–2.34 Å. In the third Tm3+ site, Tm3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 49–59°. There are a spread of Tm–O bond distances ranging from 2.23–2.32 Å. In the fourth Tm3+ site, Tm3+ is bonded to sixmore »
