Unusual H-bonding in novel cyano-cluster polymeric hydrates [(H){Ln(H2O)4}{Re6S8(CN)6}]*2H2O (Ln = Yb, Lu).
X-Ray studies and (1)H NMR measurements for novel cyano-bridged polymers [(H){Ln(H(2)O)(4)}{Re(6)S(8)(CN)(6)}]*2H(2)O (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.
