The physical properties of the following three complexes were investigated ClF3.BF3, ClF3.AsF5 and ClF3.SbF5. A vacuum line was built to handle ClF3 and its complexes safely with the exclusion of atmospheric moisture for vapor pressure determination, conductivity measurement and preparation of NMR samples. Vapor pressure meas urements gave indication of strong bonding with AsF5 and SbF5 even at room temperature. With BF3 the complex was somewhat weaker. NMR in vestigations were conducted with these complexes in ClF3 as solvent. Indirect qualitative proof was obtained for the existence of the ionic structure. The results could not be evaluated quantitatively because of the rapid fluorine exchange between ClF3 and the complexes. A conductivity cell was designed for measuring the conductivity of the complexes in ClF3 as solvent. In each case a .001 to .0001-fold increase was noted in the conductivity in a concentration less than 10 mol percent. A low temperature IR cell was designed. Sodium chloride windows were un satisfactory for working with ClF3. IRTRAN-2 windows showed no corrosion.
