Abstract

A textbook dysprosium dinuclear complex based on acetylacetone ligands, [Dy₂ (acac)₄ (μ₂ -acac)₂ (H₂ O)₂ ], has been synthesized and fully characterized. This simple dimeric lanthanide complex shows well-resolved solid-state luminescence and behaves as a single-molecule magnet under zero DC field. A seminal crystal-field approach is used to marry both magnetism and luminescence in the frame of an energetic picture.

Keywords: crystal field; dysprosium; luminescence; single-molecule magnets; supramolecular chemistry.
