Single molecule magnet behavior observed in a 1-D dysprosium chain with quasi-D-5h symmetry

Two one-dimensional (1-D) chain complexes with pentagonal bipyramidal Dy-III centers have been synthesized and magnetically characterized. Field-induced single molecule magnet behavior has been revealed in both compounds, which is still rarely reported in a lanthanide compound with a pentagonal bipyramidal coordination geometry. Their crystal field parameters and orientations of the magnetic easy axes were obtained from the simulation of the magnetic data and the electrostatic model calculation.
