Ligand substitution effect on single-molecule magnet behavior in dinuclear dysprosium complexes with radical functionalized phenol as bridging ligands†
Abstract
Reaction of Dy(hfac)3·2H2O (hfac = hexafluoroacetyl acetonate) with 2-(2-hydroxyphenyl)nitronyl nitroxide (NITPhOH) and 2-(5-bromo-2-hydroxyphenyl)nitronyl nitroxide (NIT5BrPhOH) yielded [Dy2(hfac)4(NITPhO)2] 1 and [Dy2(hfac)4(NIT5BrPhO)2] 2, respectively. These compounds are phenoxo-O bridged binuclear complexes with the radical unit of a
