摘要：

Four ionic iron(III) and manganese(III) dipicolinato complexes of the formula (2-pymeH) [Fe-III(dipic)(2)]center dot[Fe-III(H2O)(2)Cl(dipic)center dot H2O, (3-pymeH)Mn-III(dipic)(2)]center dot 1.5H(2)O, (4-pymeH)[Fe-III(dipic)(2)]center dot 2H(2)O and (4-pymeH)[Mn-III(dipic)(2)]-2H(2)O, where H(2)dipic = pyridine-2,6-dicarboxylic acid, 2-pyme = 2-pyridinemethanol, 3-pyme = 3-pyridinemethanol, 4-pyme = 4-pyridinemethanol, have been prepared and characterized by the single-crystal X-ray structure analysis, infrared spectroscopy and magnetic measurements. The magnetic data were fitted to a zero-field splitting model revealing a slight magnetic anisotropy for Mn(III) systems. The molecular field correction was consistently formulated and included in the analysis for both, magnetic susceptibility and magnetization data. (C) 2014 Elsevier B.V. All rights reserved.
