The Difference

In this work, the synthesis, structure, and magnetic studies of three dinuclear Dy2 compounds, namely Dy2(bpy)2(L)6 (1), Dy2(phen)2(L)6 (2), Dy2(μ-H2O)2(bpy)2(L)6 (3) are reported in detail, where HL, phen, and bpy are 4-chlorobenzoic acid, 1,10-phenanthroline, and 2,2′-bipyridine. Magnetic studies reveal the intramolecular ferromagnetic interaction and single-molecule magnetic properties of these compounds. The fine-tuned single-molecule magnet properties of compounds 1–3, mainly due to the difference of the coordination geometry of DyIII ions, are highlighted.

High local coordination symmetry around the spin center and the alignment between magnetic and symmetric axes together play a crucial role in single-molecule magnet performance
