Abstract
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.
