Zn3(GaTe3)2 crystallizes in the monoclinic C2 space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one Te(1), one Te(2), and two equivalent Te(3) atoms to form ZnTe4 tetrahedra that share corners with two equivalent Zn(1)Te4 tetrahedra, corners with three equivalent Zn(2)Te4 tetrahedra, and corners with five equivalent Ga(1)Te4 tetrahedra. In the second Zn site, Zn(2) is bonded to two equivalent Te(2) and two equivalent Te(3) atoms to form ZnTe4 tetrahedra that share corners with four equivalent Ga(1)Te4 tetrahedra and corners with six equivalent Zn(1)Te4 tetrahedra. Ga(1) is bonded to one Te(2), one Te(3), and two equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with two equivalent Zn(2)Te4 tetrahedra, corners with two equivalent Ga(1)Te4 tetrahedra, and corners with five equivalent Zn(1)Te4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a trigonal non-coplanar geometry to one Zn(1) and two equivalent Ga(1) atoms. In the second Te site, Te(2) is bonded in a trigonal non-coplanar geometry to one Zn(1), one Zn(2), and one Ga(1) atom. In the third Te site, Te(3) is bonded to one Zn(2), two equivalent Zn(1), and one Ga(1) atom to form corner-sharing TeZn3Ga tetrahedra.
