(Sr)2LiTc crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one LiTc cluster and one Sr cluster. In the LiTc cluster, Li(1) is bonded in a single-bond geometry to one Tc(1) atom. The Li(1)-Tc(1) bond length is 0.10 Å. Tc(1) is bonded in a single-bond geometry to one Li(1) atom. In the Sr cluster, Sr(1) is bonded in a single-bond geometry to one Sr(1) atom. The Sr(1)-Sr(1) bond length is 0.47 Å.
