AsTc(Ga)2 is alpha oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one gallium molecule and one AsTc cluster. In the AsTc cluster, Tc(1) is bonded in a single-bond geometry to one As(1) atom. The Tc(1)-As(1) bond length is 0.40 Å. As(1) is bonded in a single-bond geometry to one Tc(1) atom.
