A dinuclear dysprosium single-molecule magnet constructed by o-vanillin Schiff base ligand: Magnetic properties and solution behaviour

A novel dinuclear dysprosium complex, [Dy2(L)2(DBM)2(DMF)2]·3CH3OH (1) (H2L = 2-((2-hydroxy-3-methoxybenzylidene)amino)acetic acid, HDBM = dibenzoylmethane), was synthesized, structurally and magnetically characterized. Electrospray ionization mass spectrometry (ESI-MS) results revealed that the intact framework of complex 1 stable in methanol solution. Magnetic susceptibilities to an alternating current revealed that complex 1 exhibits single-molecule magnet behaviour.95
