Materials Data on Ba7Sn3Te3Se10 by Materials Project
Abstract
Ba7Sn3Te3Se10 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to three equivalent Te2- and six Se2- atoms. There are a spread of Ba–Te bond distances ranging from 3.60–3.75 Å. There are a spread of Ba–Se bond distances ranging from 3.42–3.70 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to two Te2- and six Se2- atoms. There are one shorter (3.56 Å) and one longer (3.78 Å) Ba–Te bond lengths. There are a spread of Ba–Se bond distances ranging from 3.37–3.94 Å. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to two equivalent Te2- and six Se2- atoms. There are one shorter (3.51 Å) and one longer (3.80 Å) Ba–Te bond lengths. There are a spread of Ba–Se bond distances ranging from 3.35–3.49 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to two Te2- and five Se2- atoms. There are one shorter (3.45 Å) and one longer (3.95 Å) Ba–Te bond lengths. There are a spread of Ba–Se bond distances ranging from 3.25–3.67 Å. There aremore »
