| Abstract: | A textbook dysprosium dinuclear complex based on acetylacetone ligands, [Dy2(acac)4(μ2-acac)2(H2O)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. |
