Mg Sb Te
MgSbTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgSbTe clusters. Mg(1) is bonded in a linear geometry to one Sb(1) and one Te(1) atom. The Mg(1)-Sb(1) bond length is 0.28 Å. The Mg(1)-Te(1) bond length is 0.79 Å. Sb(1) is bonded in a single-bond geometry to one Mg(1) atom. Te(1) is bonded in a single-bond geometry to one Mg(1) atom.
