SrTcZn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrTcZn cluster. Sr(1) is bonded in a single-bond geometry to one Zn(1) atom. The Sr(1)-Zn(1) bond length is 1.75 Å. Tc(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Tc(1)-Zn(1) bond length is 1.70 Å. Zn(1) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Tc(1) atom.
