Abstract

A new Fe(II)-Fe(III) alternating single chain magnet, catena-[Fe^II(ClO₄)(H₂O){Fe^III(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 χ_m^″, 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.
