Abstract : The nitrosonium NO ion absorbs in the infrared between 1/2400 and 1/ 2150 cm. Salts of complex fluoro-acids absorb at higher frequencies than salts of complex chloro-acids. NO and N2O4 react with beta-group metal halides to give solid adducts. Infrared spectroscopic examination has shown that metal halide adducts generally contain nitrosonium ions. Hexaphenylditin does not undergo marked heterolytic dissociation in nitromethane solution. Triphenyltin fluoroborate borate can be prepared from solution in organic solvents but much solvent is always carried down with the compound. New salts containing the triphenylmethyl carbonium ion and the SiF6(2-) and TiF6(2-) anions have been prepared and this cation has been identified in the substance Ph3C()Br5(-). Organometallic derivatives con containing unsaturated linkages appear to be readily protonated in solution in acid. The factors influencing the covalent-ionic equilibrium are discussed. Infrared spectrum nitrosonium ion; ionic character in lattice and position nitrosonium ion absorption; interaction nitrogen oxides and Lewis acids; onium salts containing predominatly organic or organometallic cations, factors affect covalent ionic equilibrium; synthesis triphenylmethyl carbonium ion salts.
