Treatment of p-ferrocenylbenzoate [p-HOOCH4C6Fc, Fc=(η5-C5H5)Fe(η5-C5H5)] with Mn(OAc)2·2H2O or Cd(OAc)2·2H2O afforded one-dimensional linear chain polymer {[Mn(OOCH4C6Fc)2(μ2-OH2)(H2O)2](H2O)}n (1), double-bridge polymer [Mn(μ2-OOCH4C6Fc)2(phen)]n (phen) phenanthroline) (2), and ladderlike framework {[Cd(μ2-OOCH4C6Fc)(η2-OOCH4C6Fc)(bbp)](CH3OH)}n (bbp=4,4'-trimethylene-dipyridine) (3). The solution-state cyclic voltammograms indicate that the half-wave potentials of the ferrocenyl moieties in these polymers are all shifted to positive potential compared to that of sodium p-ferrocenylbenzoate. Both 1 and 2 behave as 1D Heisenberg Mn(Ⅱ) chains with weak intrachain antiferromagnetic interactions between the local high-spin Mn(Ⅱ) ions, and the exchange coupling parameters J (-5.20 and -3.25cm-1 for 1 and 2, respectively) are larger than those of most of the reported di-Mn(Ⅱ) complexes that contain μ2-aqua and μ2-carboxylato units and one-dimensional Mn(Ⅱ) carboxylic polymers.
