Abstract

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.
