Tc3Sn is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted body-centered cubic geometry to four equivalent Tc(2) and four equivalent Sn(1) atoms. In the second Tc site, Tc(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Tc(1) and six equivalent Sn(1) atoms. Sn(1) is bonded in a distorted body-centered cubic geometry to six equivalent Tc(2) and eight equivalent Tc(1) atoms.
