The reaction of manganese(II) salts with organophosphonic
acid
[t-BuPO3H2 or cyclopentyl phosphonic
acid (C5H9PO3H2)] in the
presence of ancillary nitrogen ligands [1,10-phenanthroline (phen)
or 2,6-bis(pyrazol-3-yl)pyridine (dpzpy)], afforded, depending on
the stoichiometry of the reactants and the reaction conditions, dinuclear,
trinuclear, and tetranuclear compounds, [Mn2(t-BuPO3H)4(phen)2]·2DMF (1), [Mn3(C5H9PO3)2(phen)6](ClO4)2·7CH3OH (2), [Mn3(t-BuPO3)2(dpzpy)3](ClO4)2·H2O (3), [Mn4(t-BuPO3)2(t-BuPO3H)2(phen)6(H2O)2](ClO4)2 (4), and [Mn4(C5H9PO3)2(phen)8(H2O)2](ClO4)4 (5). Magnetic studies on 1, 2, and 4 reveal that the phosphonate bridges mediate weak antiferromagnetic
interactions between the MnII ions have also been carried
out.
