Tc5Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Tc5Sn cluster. There are five inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 2-coordinate geometry to one Tc(2), one Tc(5), and one Sn(1) atom. The Tc(1)-Tc(2) bond length is 0.29 Å. The Tc(1)-Tc(5) bond length is 1.10 Å. The Tc(1)-Sn(1) bond length is 1.84 Å. In the second Tc site, Tc(2) is bonded in a single-bond geometry to one Tc(1) atom. In the third Tc site, Tc(3) is bonded in a bent 150 degrees geometry to one Tc(4) and one Sn(1) atom. The Tc(3)-Tc(4) bond length is 0.55 Å. The Tc(3)-Sn(1) bond length is 1.54 Å. In the fourth Tc site, Tc(4) is bonded in a single-bond geometry to one Tc(3) atom. In the fifth Tc site, Tc(5) is bonded in a 2-coordinate geometry to one Tc(1) and one Sn(1) atom. The Tc(5)-Sn(1) bond length is 1.70 Å. Sn(1) is bonded in a 3-coordinate geometry to one Tc(1), one Tc(3), and one Tc(5) atom.
