MgCrTe2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgCrTe2 clusters. Mg(1) is bonded in a 2-coordinate geometry to one Te(1) and one Te(2) atom. The Mg(1)-Te(1) bond length is 0.56 Å. The Mg(1)-Te(2) bond length is 0.59 Å. Cr(1) is bonded in a 2-coordinate geometry to one Te(1) and one Te(2) atom. The Cr(1)-Te(1) bond length is 0.49 Å. The Cr(1)-Te(2) bond length is 0.49 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 3-coordinate geometry to one Mg(1), one Cr(1), and one Te(2) atom. The Te(1)-Te(2) bond length is 0.39 Å. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one Mg(1), one Cr(1), and one Te(1) atom.
