Dinuclear, tetrakis(acetato)-bridged lanthanide(III) complexes from the use of 2-acetylpyridine hydrazone

• 2-Acetylpyridine hydrazone has been used as ligand in lanthanide(III) chemistry.
• Dinuclear, quadruply acetato-bridged lanthanide complexes have been isolated.
• Weak intramolecular antiferromagnetic DyIII⋯DyIII interactions are present.

The first employment of 2-acetylpyridine hydrazone in lanthanide(III) chemistry has led to dinuclear complexes with four bridging acetate groups of two different types and chelating 2-acetylpyridine hydrazone ligands.

The use of the 2-acetylpyridine hydrazone/acetate/nitrate ligand “blend” in lanthanide(III) chemistry has resulted in dinuclear complexes containing two bridging and two bridging–chelating acetate groups, as well as chelating hydrazone and nitrato ligands.Figure optionsDownload as PowerPoint slide
