SrTcAu2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrTcAu2 clusters. Sr(1) is bonded in a linear geometry to one Tc(1) and one Au(1) atom. The Sr(1)-Tc(1) bond length is 0.16 Å. The Sr(1)-Au(1) bond length is 0.94 Å. Tc(1) is bonded in a linear geometry to one Sr(1) and one Au(2) atom. The Tc(1)-Au(2) bond length is 1.10 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second Au site, Au(2) is bonded in a single-bond geometry to one Tc(1) atom.
