The two apical C1-F bonds are elongated (1.70 1) compared to the equatorial C1-F bond (1.60 A). The bond angles are 87.5' <strong>and</strong> 175'. The l9F NMR of gaseous CLF3 shows the apical fluorines to be further downfield (-145.6 @) than the equatorial fluorine -19.7 @. In liquid ClF3 (<strong>with</strong> HF carefully removed) the resonances are -159.0 <strong>and</strong> -21.8 6. The high dipole moment determined <strong>with</strong> the liquid (1.00-1.03 D) compared to that in the gas (- 0.6 D) suggests corn iderable interaction <strong>and</strong> the relatively low volatility (b.p. 12') confirms this, but the electrjcal conductivity shows that this interaction is essentially not in the form of self-ionization to CLF2+ <strong>and</strong> ClF4- ions. Evidence for some dimerization in the gas has been suggested. However stable <strong>salt</strong>s of both of these ions are known, e.g., Cp2+SbF6- <strong>and</strong> Cs+ClF4-. Chlorine trifluoride is commercially available in quantity, being prepared by fluorination of chlorine. It is an extremely vigorous fluorinating agent, but can in turn be fluorinated to ClF5 under pressure. Moisture converts CLF3 to C102F <strong>and</strong> C102. I Chlorine pentafluoride is the newest member of the halogen fluoride family <strong>and</strong> has very recently become available commercially in laboratory quantities. It is prepared by the high pressure fluorination of ClF3 or a <strong>salt</strong> such as CsClF4 at 150' or above. It has also been prepared by the fluorination of CLF3 under ultraviolet radiation or electric discharge at low temperatures <strong>and</strong> by platinum hexafluoride. The structure of CU5, a square pyramid, is an octahedral derivative <strong>with</strong> the apical C1-F bond length of 1.62 1 <strong>and</strong> the equatorial bonds 1.72 A. The I9F chemical shifts are -412 $ (apical fluorine) <strong>and</strong> -247 6 (basal fluorines). The former is one Of the most unshielded fluorine atoms known, being exceeded only by those in F2, 02F2, <strong>and</strong> NOF. The dipole moment is probably 0.2-0.4 D. The boiling point indicates very little interaction exists in the liquid <strong>and</strong> self-ionization is not expected. The C-4' ion is an intense peak in the mass spectrum <strong>and</strong> the possibility of obtaining --
