Ga2Te3 crystallizes in the monoclinic Cc space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one Te(1), one Te(3), and two equivalent Te(2) atoms to form corner-sharing GaTe4 tetrahedra. In the second Ga site, Ga(2) is bonded to one Te(1), one Te(2), and two equivalent Te(3) atoms to form corner-sharing GaTe4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a water-like geometry to one Ga(1) and one Ga(2) atom. In the second Te site, Te(2) is bonded in a trigonal non-coplanar geometry to one Ga(2) and two equivalent Ga(1) atoms. In the third Te site, Te(3) is bonded in a trigonal non-coplanar geometry to one Ga(1) and two equivalent Ga(2) atoms.

In the first Ga site, Ga(1) is bonded to one Te(1), one Te(3), and two equivalent Te(2) atoms to form corner-sharing GaTe4 tetrahedra. The Ga(1)-Te(1) bond length is 2.56 Å. The Ga(1)-Te(3) bond length is 2.68 Å. There is one shorter (2.67 Å) and one longer (2.68 Å) Ga(1)-Te(2) bond length. In the second Ga site, Ga(2) is bonded to one Te(1), one Te(2), and two equivalent Te(3) atoms to form corner-sharing GaTe4 tetrahedra. The Ga(2)-Te(1) bond length is 2.58 Å. The Ga(2)-Te(2) bond length is 2.66 Å. There is one shorter (2.68 Å) and one longer (2.69 Å) Ga(2)-Te(3) bond length. There are three inequivalent Te sites.
