Sr4TcCl is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Sr4TcCl clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Sr(1)-Tc(1) bond length is 3.24 Å. In the second Sr site, Sr(2) is bonded in a distorted linear geometry to one Tc(1) and one Cl(1) atom. The Sr(2)-Tc(1) bond length is 2.84 Å. The Sr(2)-Cl(1) bond length is 2.32 Å. Tc(1) is bonded in a 4-coordinate geometry to one Sr(2) and three equivalent Sr(1) atoms. Cl(1) is bonded in a single-bond geometry to one Sr(2) atom.
