Synthesis, structure, and magnetic property of a new Fe(II)–Fe(III) alternating single-chain magnet constructed with a methyl-substituted bpca− ligand
چکیده انگلیسی

A new Fe(II)–Fe(III) alternating single chain magnet, catena-[FeII(ClO4)(H2O){FeIII(bmpca)2}](ClO4)2, was synthesized using methyl-substituted bpca− ligand, bmpca− (Hbpca and Hbmpca denote bis(2-pyridylcarbonyl)amine and bis(4-methyl-2-pyridylcarbonyl)amine, respectively). The one-dimensional complex shows the ferrimangetic behavior and frequency dependent out-of-phase ac susceptibility χm″, with the α parameter of 0.25 estimated by the semicircle Cole–Cole plot. The activation energy Δ was estimated to be 19(1) K from an Arrhenius plot.

A new Fe(II)–Fe(III) alternating single chain magnet, catena-[FeII(ClO4)(H2O){FeIII(bmpca)2}](ClO4)2, was synthesized using methyl-substituted bpca− ligand, bmpca− (Hbpca and Hbmpca denote bis(2-pyridylcarbonyl)amine and bis(4-methyl-2-pyridylcarbonyl)amine, respectively).Figure optionsDownload as PowerPoint slide
