Abstract:
The reduction processes of the volatile hexafluorides TeF6 and SeF6 have been studied in CH2Cl2 using electrochemical methods with a vacuum-tight electrochemical cell. At -78-degrees-C the half-wave potential for the [TeF6]0/2- step occurs at - 0.88 V vs. SCE, while the less reversible [SeF6]0/2- reduction is observed at the more positive potential, E1/2 = - 0.1 V. The complex ion [TeF7]- is irreversibly reduced in MeCN at - 0.7 V. These results are interpreted using an orbital framework. The results of Extended Huckel calculations on model systems are discussed. In each case, reduction results in the population of a metal-ligand antibonding orbital which is dominated by the metal valence s orbital.
