Formation of anionic fluoride-complexes of element 104, rutherfordium, produced in the 248Cm(18O, 5n)261Rf reaction was studied by anion-exchange on an atom-at-a-time scale. It was found that the hexafluoro complex of Rf, [RfF6]2-, was formed in the studied fluoride ion concentrations of 0.0005-0.013 M. Formation of [RfF 6]2- was significantly different from that of the homologues Zr and Hf, [ZrF6]2- and [HfF6] 2-; the evaluated formation constant of [RfF6] 2- is at least one-order of magnitude smaller than those of [ZrF 6]2- and [HfF6]2-.
