The crystal structure described by Ga7Te10 crystallizes in the trigonal R32 space group. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one Ga(1) and three equivalent Te(4) atoms to form corner-sharing GaGaTe3 tetrahedra. In the second Ga site, Ga(2) is bonded to one Te(2), one Te(4), and two equivalent Te(5) atoms to form GaTe4 tetrahedra that share  a cornercorner with one Ga(1)GaTe3 tetrahedra,  a cornercorner with one Ga(2)Te4 tetrahedra, corners with three equivalent Ga(3)Te4 tetrahedra, and  an edgeedge with one Ga(2)Te4 tetrahedra. In the third Ga site, Ga(3) is bonded to one Te(1), one Te(3), one Te(4), and one Te(5) atom to form GaTe4 tetrahedra that share  a cornercorner with one Ga(1)GaTe3 tetrahedra, corners with three equivalent Ga(2)Te4 tetrahedra, and corners with three equivalent Ga(3)Te4 tetrahedra. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded in a trigonal non-coplanar geometry to three equivalent Ga(3) atoms. In the second Te site, Te(2) is bonded in an L-shaped geometry to two equivalent Ga(2) atoms. In the third Te site, Te(3) is bonded in a water-like geometry to two equivalent Ga(3) atoms. In the fourth Te site, Te(4) is bonded in a trigonal non-coplanar geometry to one Ga(1), one Ga(2), and one Ga(3) atom. In the fifth Te site, Te(5) is bonded in a distorted T-shaped geometry to one Ga(3) and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
