A rare chloride-bridged dysprosium chain with slow magnetic relaxation: a thermally activated mechanism via a second-excited state promoted by magnetic interactions

Abstract

A novel superparamagnetic dysprosium chain complex, namely, [Dy(L)Cl(CH3OH)]n (1) (H2L = N′-(5-bromo-2-hydroxybenzylidene)pyrazine-N-oxide-carbohydrazide), has been successfully synthesized by the extension of dinuclear units through chloride bridges. Magnetic and theoretical studies indicate that dipolar magnetic interactions induced by the chloride bridges are helpful for the magnetic relaxation process to pass through the second-excited state of dysprosium ions, resulting in the higher energy barrier for 1.
