| Popis: | A complex electron diffraction and mass spectrometric investigation of the saturated vapor of rhenium tetrafluoride has been carried out. The principal molecular form in the vapor phase at T=471 K is the dimer Re2F8. The geometric structure of the Re2F8 molecule has the equilibrium eclipsed conformation of symmetry D4h with a triple bond, Re≡Re. The barrier to internal rotation of the ReF4 groups relative to one another is 2.8±2.8 kJ/mole. The vibration frequencies of the Re2F8 molecule have been estimated on the basis of the experimental amplitudes of vibration. |
