ZnGa2S4 crystallizes in the tetragonal I-4 space group. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with four equivalent Ga(1)S4 tetrahedra and corners with four equivalent Ga(2)S4 tetrahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent S(1) atoms to form GaS4 tetrahedra that share corners with four equivalent Zn(1)S4 tetrahedra and corners with four equivalent Ga(2)S4 tetrahedra. In the second Ga site, Ga(2) is bonded to four equivalent S(1) atoms to form GaS4 tetrahedra that share corners with four equivalent Zn(1)S4 tetrahedra and corners with four equivalent Ga(1)S4 tetrahedra. S(1) is bonded in a trigonal non-coplanar geometry to one Zn(1), one Ga(1), and one Ga(2) atom.
