SrTcBr crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrTcBr clusters. Sr(1) is bonded in a linear geometry to one Tc(1) and one Br(1) atom. The Sr(1)-Tc(1) bond length is 0.42 Å. The Sr(1)-Br(1) bond length is 0.74 Å. Tc(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. Br(1) is bonded in a distorted single-bond geometry to one Sr(1) atom.
