Tuning spin dynamics of binuclear Dy complexes using different nitroxide biradical derivatives

Abstract

Employing nitronyl/imino nitroxide biradicals, three Ln-Zn complexes, namely, [Ln2Zn2(hfac)10(ImPhPyobis)2] (LnIII = Gd 1, Dy 2; hfac = hexafluoroacetylacetonate; ImPhPyobis = 5-(4-oxypyridinium-1-yl)-1,3-bis(1-oxyl-4,4,5,5-tetramethyl-4,5-hydro-1H-imidazol-2-yl)benzene) and [Dy2Zn2(hfac)10(NITPhPyobis)2] 3 (NITPhPyobis = 5-(4-oxypyridinium-1-yl)-1,3-bis(1-oxyl-3-oxido-4,4,5,5-tetramethyl-4,5-hydro-1H-imidazol-2-yl)benzene) have been successfully...
