Crystal structures of the tetragonal forms of germanium and silicon disulfide are similar and consist of (SiS4)4- and (GeS4)4- tetrahedra which share vertices to form three-dimensional networks. These tetragonal materials, synthesized at high pressure and temperature, are different from the previously known germanium and silicon disulfides.
