MgTcGa crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgTcGa cluster. Mg(1) is bonded in a linear geometry to one Tc(1) and one Ga(1) atom. The Mg(1)-Tc(1) bond length is 0.98 Å. The Mg(1)-Ga(1) bond length is 1.27 Å. Tc(1) is bonded in a single-bond geometry to one Mg(1) atom. Ga(1) is bonded in a single-bond geometry to one Mg(1) atom.
