Ga2Te5 crystallizes in the tetragonal I4/m space group. Ga(1) is bonded to four equivalent Te(1) atoms to form edge-sharing GaTe4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded in a square co-planar geometry to four equivalent Te(1) atoms. In the second Te site, Te(1) is bonded in a 3-coordinate geometry to two equivalent Ga(1) and one Te(2) atom.
