Materials Data on TcSnSe by Materials Project
TcSnSe is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Tc1- is bonded in a 10-coordinate geometry to four equivalent Sn3+ and six equivalent Se2- atoms. All Tc–Sn bond lengths are 2.83 Å. All Tc–Se bond lengths are 3.26 Å. Sn3+ is bonded in a body-centered cubic geometry to four equivalent Tc1- and four equivalent Se2- atoms. All Sn–Se bond lengths are 2.83 Å. Se2- is bonded to six equivalent Tc1- and four equivalent Sn3+ atoms to form a mixture of distorted corner and face-sharing SeTc6Sn4 tetrahedra.
