Slow relaxation of magnetization and luminescence in seven- and six-coordinate Tbandlt-supandgt-3+ andlt-/supandgt-complexes
Abstract
The synthesis, structures, magnetic and luminescent properties of a new series of mononuclear Tb3+ complexes, such as {Tb[OCH(CF3)Ph]2(THF)5}[BPh4], [Tb(OC6F4C6F5)2(THF)5][BPh4], {Tb[OC(CF3)2Ph]2(THF)4} [BPh4] and {Tb[OC(CF3)3]3(THF)3}, in which fluorinated alkoxide ligands with different steric bulk afford different geometries of the Tb center, are reported. The compound {Tb[OCH(CF3)Ph]2(THF)5}[BPh4], which adopts a pentagonal bipyramidal geometry with an axial O–Tb–O angle of 177.7(5)° and short Tb–O distances, behaves as a field-induced single molecule magnet. All complexes exhibit characteristic Tb3+ emission with a relatively long lifetime of up to 1.7 ms.
