Ways of reducing perrhenates to rhenides as well as the isolation of various metal rhenides and their purification are described. Some physical and chemical properties of rhenides are reported. Alkali metal and barium rhenides are white crystals easily soluble in water and exhibit all of the typical properties of ionic compounds. The pure salts are stable in vacuo or in an inert atmosphere. They are oxidized by air; the rate of oxidation, however, is retarded if the rhenides are contaminated with hydroxides. Results of earlier work concerning the preparation of a colorless form of ammontum radical in liquid ammonia were not confirmed by current work. This, however, could be attributed to catalytic effects of trace contaminations present. Solutions of ammonium borohydride in liquid ammonia in various concentrations and solid ammonium borohydride were prepared by reacting potassium borohydride and ammonium chloride in liquid ammonia. This compound was synthesized earlier by reacting sodium borohydride with ammonium fluoride in liquid ammonia. Advantages and disadvantages of these two methods are discussed. (auth)
