A mixture of NF3, BF3, and F2 excess, when subjected to glow discharge at -78 degrees, formed a white, nonfuming, easily hydrolyzable solid. The compound consists of CuF2 interaction with the copper electrodes, N2FBF4-, traces of NOBF4-, and perhaps some CuBF4-2. There is no evidence for the desired NF4BF5- nor for any NF sub x cation, where x 1, 2, 3, or 4. In a separate experiment, ultraviolet irradiation of a mixture of NF3, AsF5, and F2 excess using a -78 degree coolant, showed interaction of the components by the formation of a solid and by a total pressure decrease. However, experimental difficulties prevented identification of the solid product. Oxygen difluoride, AsF5, and F2 excess, when subjected to glow discharge at -78 degrees, react to form a white hygroscopic powder. The solid fumes slightly and gives off an ozone-like smell on exposure to moist air. Commercial F2 98, when subjected to glow discharge at -78 degrees produced some NF3 but no solid compound. The glow discharge of AsF5 and F2 excess at -78 degrees resulted in the formation of NF4AsF6-.
