Materials Data on Tc3Sn by Materials Project

Abstract

Tc3Sn is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Tc+1.33- sites. In the first Tc+1.33- site, Tc+1.33- is bonded in a distorted body-centered cubic geometry to four equivalent Tc+1.33- and four equivalent Sn4+ atoms. All Tc–Tc bond lengths are 2.75 Å. All Tc–Sn bond lengths are 2.75 Å. In the second Tc+1.33- site, Tc+1.33- is bonded in a distorted body-centered cubic geometry to eight equivalent Tc+1.33- and six equivalent Sn4+ atoms. All Tc–Sn bond lengths are 3.17 Å. Sn4+ is bonded in a distorted body-centered cubic geometry to fourteen Tc+1.33- atoms.
