Three new lanthanide complexes based on a novel nitronyl nitroxide radical [Ln(hfac)3(NITPhiPr)2] (Ln = Gd(1), Tb(2), Dy(3); hfac = hexafluoroacetylacetonate, NITPhiPr = 4′-isopropyl-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) have been successfully synthesized, characterized structurally and magnetically, which all display radical-Ln(III)-radical tri-spin structures. The magnetic studies reveal the ferromagnetic interactions between the Gd(III) ion and radicals and the antiferromagnetic interaction between two radicals in the complex 1. And both Ln(III)–radical ferromagnetic interactions exist in complexes 2 and 3.
A novel radical and its three mononuclear Gd (III), Tb (III), Dy (III) tri-spin complexes were successfully synthesized and characterized magnetically. The magnetic studies reveal that all lanthanide–radical ferromagnetic interactions exist in complexes 1–3.Figure optionsDownload as PowerPoint slideHighlights
► Three lanthanide–radical complexes were successfully synthesized.
► All ferromagnetic interactions exist in complexes 1–3.
► Simplified model was carried out to evaluate the coupling in complex 1.
