ZnGa2S4 crystallizes in the tetragonal I-42m space group. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with eight equivalent Ga(1)S4 tetrahedra. 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(1)S4 tetrahedra. S(1) is bonded in a trigonal non-coplanar geometry to one Zn(1) and two equivalent Ga(1) atoms.
