K2TcSn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2TcSn clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Sn(1) atom. The K(1)-Sn(1) bond length is 1.15 Å. In the second K site, K(2) is bonded in a linear geometry to one Tc(1) and one Sn(1) atom. The K(2)-Tc(1) bond length is 0.49 Å. The K(2)-Sn(1) bond length is 1.15 Å. Tc(1) is bonded in a single-bond geometry to one K(2) atom. Sn(1) is bonded in a linear geometry to one K(1) and one K(2) atom.
