cze Syntéza, krystalová struktura a magnetizmus železitých a manganitých dipikolinátů s pyridinmethanolem Čtyři iontové dipicolinátové železité a manganité komplexy obecného vzorce (2-pymeH)[Fe-III(dipic)(2)].[Fe-III(H2O)(2)Cl(dipic).H2O, (3-pymeH)Mn-III(dipic)(2)] .1,5H(2)O, (4-pymeH)[Fe-III(dipic)(2)] .2H(2)O a (4-pymeH)[Mn-III(dipic)(2)]-2H(2)O, kde H(2)dipic = pyridin-2,6-dikarboxylová kyselina, 2-pyme = 2-pyridinmethanol, 3-pyme = 3-pyridinmethanol, 4-pyme = 4-pyridinmethanol, byly připraveny a charakterizovány pomocí rentgenostrukturní analýzy na monokrystalickém materiálu, infračervené spektroskopie a magnetických měření. Magnetické údaje byly fitovány na hodnoty štěpení v nulovém poli , což odhalilo mírnou magnetickou anizotropii pro Mn(III) systémy. Byly provedeny korekce dat pro naměřenou magnetickou susceptibilitu a magnetizaci.
eng Synthesis, crystal structure and magnetism of iron(III) and manganese(III) dipicolinates with pyridinemethanols 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.
