Slow magnetic relaxation in a carboxylate-bridged one dimensional dysprosium complex

• A new carboxylate-bridged DyIII complex with 1D chain structure was synthesized.
• The complex was characterized by IR, TG, PXRD and X-ray crystallography diffraction.
• The magnetic studies indicate that the complex exhibits slow magnetic relaxation.

A new carboxylate-bridged dysprosium complex, e.g. [Dy2(PAA)6]n (1, PAA−= 4-aminobenzoic acid anion), was synthesized under solvothermal conditions and fully characterized. Single crystal X-ray crystallography analysis reveals that complex 1 consists of linear chains built up by Dy2(PAA)6 units and bridged only by carboxylate groups. The magnetic studies indicate that the coordination polymer exhibits slow magnetic relaxation, suggesting single molecule magnet behavior.

A new carboxylate-bridged one dimensional dysprosium complex, e.g. [Dy2(PAA)6]n (PAA− = 4-aminobenzoic acid anion) was obtained. The complex exhibits slow relaxation of magnetization.Figure optionsDownload as PowerPoint slide
