[24], Germanium differs from silicon in that the supply is limited by the availability of exploitable sources, while the supply of silicon is limited only by production capacity since silicon comes from ordinary sand and quartz. CS2 has two S atoms, hence, the valence electrons in sulfur here are 6*2=12. The deposits in China are located mainly in the lignite mines near Lincang, Yunnan; coal is also mined near Xilinhaote, Inner Mongolia.[55]. The chalcogenide framework of the aerogels prepared from main group Zintl clusters and Pt 2+ has a colloidal structure and a disordered pore system, similar to that seen in base-catalyzed silica, as exemplified by Pt 2 [Ge 4 S 10] (Figure 17.3) [].Like the GeS x aerogels discussed in Sect.
