Treatment of p-ferrocenylbenzoate [p-HOOCH(4)C(6)Fc, Fc = (eta(5)-C5H5)Fe(eta(5)-C5H5)] with Mn(OAc)(2)-2H(2)O or Cd(OAC)(2).2H(2)O afforded one-dimensional linear chain polymer {[Mn(OOCH4C6FC)(2)(mu(2)-OH2)(H2O)(2)](H2O)}(n) (1), double-bridge polymer [Mn(mu(2)-OOCH(4)C(6)Fc)(2)(phen)](n) (phen = phenanthroline) (2), and ladderlike framework {[Cd(mu(2)-OOCH(4)C(6)Fc)(eta(2)-OOCH(4)C(6)Fc)(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 1 D 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 -3.25 cm(-1) for 1 and 2, respectively) are larger than those of most of the reported di-Mn(II) complexes that contain mu(2)-aqua and mu(2)-carboxylato units and one-dimensional Mn(II) carboxylic polymers.
