Materials Data on Ba3Sn2 by Materials Project
Ba3Sn2 crystallizes in the tetragonal P4_32_12 space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a 6-coordinate geometry to six equivalent Sn atoms. There are a spread of Ba–Sn bond distances ranging from 3.55–3.97 Å. In the second Ba site, Ba is bonded in a 6-coordinate geometry to six equivalent Sn atoms. There are a spread of Ba–Sn bond distances ranging from 3.71–3.85 Å. Sn is bonded in a 10-coordinate geometry to nine Ba and one Sn atom. The Sn–Sn bond length is 3.00 Å.
