Abstract

A dinuclear dysprosium compound, [Dy2(dbm)4L2]2(1) (Hdbm=1,3-diphenyl-1,3-propanedione, HL=2-[[(4-fluorophenyl)imino]methyl]-8-hydroxyquinoline), have been synthesized, structurally and magnetically characterized. The X-ray structural analysis exhibits that the compound 1 is phenoxo-O bridged binuclear compound, in which two DyIII ions are bridged by two phenoxido oxygen atoms of two 8-hydroxyquinoline Schiff base ligands. Each DyIII centers exhibit an eight-coordinated environment. Magnetic measurements indicated that slow relaxation of the magnetization was clearly observed in 1, typical of SMM behavior.
