Reaction between gaseous nitrogen dioxide and gaseous uranium hexafluoride results in the formation of the nitrylium salt NO/sub 2/UF/sub 6/. Under similar conditions no reaction occurs between nitrogen dioxide and molybdenum and tungsten hexafluorides. Reaction between nitrosyl and nitryl fluorides and the three hexafluorides results in solid compounds of the composition NO/sub x/F x MF/sub 6/, where x is 1 or 2 and M represents Mo, W, or U. Reaction between gaseous or liquid nitrosyl chloride and molybdenum and uranium hexafluorides results in the formation of the nitrosylium salts NOMoF/sub 6/ and NOUF/sub 6/ and chlorine. Tungsten hexafluoride was found not to react with nitrosyl chloride. The conditions and stoichiometry of the reactions are described. The nitrylium salt, NO/sub 2/UF/sub 6/, is characterized, and some of its physical and chemical properties are described. The NO/sub x/F x MF/sub 6/ compounds are characterized, and some physical properties are described. Evidence for the presence of NO/sup +/ and MF/sup -//sub 7/ ions in these compounds is given. The nitrosylium salts, NOMoF/sub 6/ and NOUF/sub 6/, were characterized previously. (auth
