Phosphorus hydrides germanium halides

Of all the reactions studied, only the synthesis of nitrogen oxides and acetylene in arcs or plasma torches and that of ozone in glow and corona discharges are of major importance. In addition, a few small-scale preparations of inorganic compounds have been developed, e.g. synthesis of hydrazine and of hydrides and halides of silicon, germanium, tin, lead, phosphorus or arsenic 3> ... 

The simplest hydrides and halides of boron, silicon, germanium, phosphorus, and arsenic can be decomposed in electric discharges to form...
