Abstract
Abstract A textbook dysprosium dinuclear complex based on acetylacetone ligands, [Dy 2 (acac) 4 (μ 2 ‐acac) 2 (H 2 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.
