Mg(Te)2 is Indium-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Mg cluster and one Te cluster. In the Mg cluster, there are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a single-bond geometry to one Mg(2) atom. The Mg(1)-Mg(2) bond length is 0.33 Å. In the second Mg site, Mg(2) is bonded in a single-bond geometry to one Mg(1) atom. In the Te cluster, there are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a bent 150 degrees geometry to one Te(2) and one Te(3) atom. The Te(1)-Te(2) bond length is 0.78 Å. The Te(1)-Te(3) bond length is 1.31 Å. In the second Te site, Te(2) is bonded in a bent 150 degrees geometry to one Te(1) and one Te(4) atom. The Te(2)-Te(4) bond length is 1.31 Å. In the third Te site, Te(3) is bonded in a distorted single-bond geometry to one Te(1) atom. In the fourth Te site, Te(4) is bonded in a single-bond geometry to one Te(2) atom.
