TcSnSe is half-Heusler structured and crystallizes in the cubic F-43m space group. Tc(1) is bonded in a 10-coordinate geometry to four equivalent Sn(1) and six equivalent Se(1) atoms. Sn(1) is bonded in a body-centered cubic geometry to four equivalent Tc(1) and four equivalent Se(1) atoms. Se(1) is bonded to six equivalent Tc(1) and four equivalent Sn(1) atoms to form a mixture of distorted face and corner-sharing SeTc6Sn4 tetrahedra.
