Ge(Ga)S4 crystallizes in the orthorhombic Fdd2 space group. Ga(1) is bonded to one S(1), one S(2), one S(4), and one S(5) atom to form GaS4 tetrahedra that share  a cornercorner with one Ga(1)S4 tetrahedra and corners with three equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to one S(1), one S(3), one S(4), and one S(5) atom to form GeS4 tetrahedra that share  a cornercorner with one Ge(1)S4 tetrahedra and corners with three equivalent Ga(1)S4 tetrahedra. There are five inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one Ga(1) and one Ge(1) atom. In the second S site, S(2) is bonded in a water-like geometry to two equivalent Ga(1) atoms. In the third S site, S(3) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the fourth S site, S(4) is bonded in a water-like geometry to one Ga(1) and one Ge(1) atom. In the fifth S site, S(5) is bonded in a water-like geometry to one Ga(1) and one Ge(1) atom.
