Tc Ag Sn Sn
TcAgSn2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcAgSn2 clusters. Tc(1) is bonded in a distorted L-shaped geometry to one Sn(1) and one Sn(2) atom. The Tc(1)-Sn(1) bond length is 1.05 Å. The Tc(1)-Sn(2) bond length is 0.74 Å. Ag(1) is bonded in a distorted single-bond geometry to one Sn(1) atom. The Ag(1)-Sn(1) bond length is 0.94 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to one Tc(1) and one Ag(1) atom. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Tc(1) atom.
