Ga3AsTe3 crystallizes in the orthorhombic Pmn2_1 space group. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one Te(2) and three equivalent Te(1) atoms to form GaTe4 tetrahedra that share  a cornercorner with one Ga(2)Te3As tetrahedra and corners with six equivalent Ga(1)Te4 tetrahedra. In the second Ga site, Ga(2) is bonded to one As(1), one Te(2), and two equivalent Te(3) atoms to form GaTe3As tetrahedra that share  a cornercorner with one Ga(1)Te4 tetrahedra, corners with two equivalent Ga(2)Te3As tetrahedra, and corners with five equivalent Ga(3)TeAs3 tetrahedra. In the third Ga site, Ga(3) is bonded to three equivalent As(1) and one Te(3) atom to form GaTeAs3 tetrahedra that share corners with five equivalent Ga(2)Te3As tetrahedra and corners with six equivalent Ga(3)TeAs3 tetrahedra. As(1) is bonded to one Ga(2) and three equivalent Ga(3) atoms to form corner-sharing AsGa4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a trigonal non-coplanar geometry to three equivalent Ga(1) atoms. In the second Te site, Te(2) is bonded in a water-like geometry to one Ga(1) and one Ga(2) atom. In the third Te site, Te(3) is bonded in a trigonal non-coplanar geometry to one Ga(3) and two equivalent Ga(2) atoms.

The Ga(1)-Te(2) bond length is 2.59 Å. There is one shorter (2.67 Å) and two longer (2.68 Å) Ga(1)-Te(1) bond lengths. In the second Ga site, Ga(2) is bonded to one As(1), one Te(2), and two equivalent Te(3) atoms to form GaTe3As tetrahedra that share  a cornercorner with one Ga(1)Te4 tetrahedra, corners with two equivalent Ga(2)Te3As tetrahedra, and corners with five equivalent Ga(3)TeAs3 tetrahedra. The Ga(2)-As(1) bond length is 2.52 Å. The Ga(2)-Te(2) bond length is 2.60 Å. Both Ga(2)-Te(3) bond lengths are 2.70 Å. In the third Ga site, Ga(3) is bonded to three equivalent As(1) and one Te(3) atom to form GaTeAs3 tetrahedra that share corners with five equivalent Ga(2)Te3As tetrahedra and corners with six equivalent Ga(3)TeAs3 tetrahedra. There is one shorter (2.51 Å) and two longer (2.54 Å) Ga(3)-As(1) bond lengths. The Ga(3)-Te(3) bond length is 2.69 Å.
