Heterospin 2p–4f and 2p–3d–4f complexes constructed by a nitronyl nitroxide ligand: syntheses, structures and magnetic properties

Abstract

Two novel 2p-4f complexes [Ln(hfac)3(Nit-Ph-PyIm)]2·CHCl3 (Ln(III) = GdIII (1), TbIII (2)) have been obtained through reacting nitronyl nirtroxide radical ligand Nit-Ph-PyIm (2-[4-[2-(2-pyridinyl)-1H-imidazol-1-yl]-phenyl]-4,4,5,5- tetramethylimidazoline-1-oxyl-3-oxide) with Ln(hfac)32H2O (hfac = hexafluoroacetylacetonate). Interestingly, by...
