Germanium and Silicon Disulfides: Structure and Synthesis

Abstract

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.
