TcZn2Sn crystallizes in the trigonal R3m space group. Tc(1) is bonded in a 1-coordinate geometry to one Zn(1), three equivalent Zn(2), and one Sn(1) atom. The Tc(1)-Zn(1) bond length is 1.98 Å. All Tc(1)-Zn(2) bond lengths are 2.71 Å. The Tc(1)-Sn(1) bond length is 2.39 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted single-bond geometry to one Tc(1), one Zn(2), and three equivalent Sn(1) atoms. The Zn(1)-Zn(2) bond length is 2.39 Å. All Zn(1)-Sn(1) bond lengths are 2.71 Å. In the second Zn site, Zn(2) is bonded in a 7-coordinate geometry to three equivalent Tc(1), one Zn(1), and three equivalent Sn(1) atoms. All Zn(2)-Sn(1) bond lengths are 2.71 Å. Sn(1) is bonded in a 7-coordinate geometry to one Tc(1), three equivalent Zn(1), and three equivalent Zn(2) atoms.
