Observation of single-molecule magnetic behavior in dinuclear Schiff base dysprosium(III) complex

• A dinuclear Schiff-base complex was synthesized.
• A convenient and viable synthetic route is achieved.
• This complex shows single molecule magnetic behavior.

A dinuclear dysprosium(III) complex, namely [Dy2(L)2(NO3)2(MeOH)4] (1) has been synthesized by Schiff base ligand salicylidene-o-aminophenol (H2L) with Dy(NO3)3·6H2O. Single crystal X-ray diffraction reveals that the dysprosium (III) centre in the dinuclear unit is 8-coordinated bridged by the phenoxo group of two Schiff base ligands, giving a dodecahedron geometry. Magnetic susceptibility studies reveal that complex 1 shows single molecule magnetic behavior with an energy barrier of 75.9 K.
