    New ionic manganese(II/III), manganese(III) and iron(II/III) complexes of the formula [Mn-II(H2O)(2)(phen)(2)]{[Mn-III(dipic)(2)]}(2)center dot 7H(2)O, (dmphenH)[Mn-III(dipic)(2)]center dot 2H(2)O, (2,2'-bipyH)[Mn-III(dipic)(2)]center dot 3H(2)O, (4,4'-bipyH)[Mn-III(dipic)(2)]center dot 4H(2)O, [Fe-II(phen)(3)]{[Fe-III(dipic)(2)]}(2)center dot 4.83H(2)O and [Fe-II(2,2'-bipy)(3)]{[Fe-III(dipic)(2)]}(2)center dot 6.11H(2)O where dipic(2-) = pyridine-2,6-dicarboxylate anion, phen = 1,10-phenanthroline, dmphenH = 2,9-dimethyl-1,10-phenanthrolinium cation, 2,2'-bipyH = 2-(2-pyridyl)pyridinium cation, 4,4'-bipyH = 4-(4-pyridyl)pyridinium cation, have been prepared and characterized by the single-crystal X-ray structure analysis, infrared spectroscopy, and by magnetic susceptibility and magnetization measurements. A zero field splitting was found in the Mn(III) dipicolinates while an antiferromagnetic exchange interaction was present in the Fe(III) dipicolinates.
