Synthesis, crystal structure and magnetism of iron(III) and manganese(III) dipicolinates with pyridinemethanols
چکیده انگلیسی


• Four novel ionic iron(III) and manganese(III) dipicolinato complexes were prepared.
• The complexes were characterized by single-crystal X-ray structural analysis, FTIR, and magnetic measurements.
• The magnetic properties were interpreted quantitatively using the spin Hamiltonian.

Four ionic iron(III) and manganese(III) dipicolinato complexes of the formula (2-pymeH) [FeIII(dipic)2]⋅[FeIII(H2O)2Cl(dipic)]⋅2H2O, (3-pymeH)[MnIII(dipic)2]⋅1.5H2O, (4-pymeH)[FeIII(dipic)2]⋅2H2O and (4-pymeH)[MnIII(dipic)2]⋅2H2O, where H2dipic = 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.

Four ionic iron(III) and manganese(III) dipicolinato complexes with pyridinemethanol have been prepared and characterized by the single-crystal X-ray structure analysis, infrared spectroscopy and magnetic measurements. The magnetic data were quantitatively interpreted within the spin Hamiltonian approach with consistently included molecular field correction.Figure optionsDownload as PowerPoint slide
