Abstract
Reactions of SnF2 and SbF3 with TaF5 and TaCl5 in acetonitrile and dimethyl sulfoxide were studied by F-19 and Sn-119 NMR. It was found that SnF2 and SbF3 behave as fluorine donors for tantalum(V). The anionic and cationic ta ntalum fluorochloride complexes form in acetonitrile, while [TaF6](-) predo minates in dimethyl sulfoxide. Tin(II) occurs in solution in the form of fl uorine-containing polymeric cations.
