Polyoxa- and dioxapolythia[n]ruthenocenophanes were prepared by the reaction of 1,1′-diacetoxyruthenocene with α-(2-bromoethyl)-ω-bromopoly(oxyethylene) in the presence of alkali metal hydroxides and by the reaction of 1,1′-bis(2-chloroethoxy)ruthenocene with dithiolate in the presence of sodium hydroxide, respectively. The extraction ability of their compounds was excellent for mercury(II) and thallium(I) ions. The ruthenocenophanes with oxygen atoms attached to the ruthenocene nucleus showed excellent extraction ability for a silver(I) ion, although the corresponding ferrocenophane analogs decomposed in similar reaction conditions. The ruthenocenophanes formed 1 : 1 complexes with mercury(II) and silver(I) ions. 1H-NMR, electronic, and IR spectral data of their complexes showed the presence of direct electronic interaction between the mercury(II) or silver(I) ion and the ruthenium atom of ruthenocenophanes.
