Abstract

X-Ray studies and 1H NMR measurements for novel cyano-bridged polymers [(H){Ln(H2O)4}{Re6S8(CN)6}]·2H2O (Ln = Yb, Lu) reveal temperature dependence of proton localization: acid protons are trapped between nitrogen atoms at low temperatures, but can be transferred to the water sublattice at higher temperatures; this transfer resulted in intermolecular proton exchange.
