Ga Ga Tc Sb
TcGa2Sb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TcGa2Sb cluster. Tc(1) is bonded in a single-bond geometry to one Ga(2) atom. The Tc(1)-Ga(2) bond length is 0.05 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to one Ga(2) and one Sb(1) atom. The Ga(1)-Ga(2) bond length is 0.46 Å. The Ga(1)-Sb(1) bond length is 0.57 Å. In the second Ga site, Ga(2) is bonded in a 1-coordinate geometry to one Tc(1), one Ga(1), and one Sb(1) atom. The Ga(2)-Sb(1) bond length is 0.46 Å. Sb(1) is bonded in a distorted single-bond geometry to one Ga(1) and one Ga(2) atom.
