Facile formation of luminescent terbium(III) aryloxide complexes directly from terbium metal including the X-ray crystal structures of Tb(OC_6H_3Me_2-2,6)_3 (THF)_3 and Tb(oc_6h_3~iPr_2-2,6)_3(THF)_2

摘要

Direct reaction of terbium metal in refluxing isopropaol and phenols provides the luminescent terbium aryloxide species Tb(OC_6H_3Me_2-2,6)_3(THF)-3 (1) and Tb(OC_6H_3~iPr_2-2,6)_3(THF)_2 (2) in good yield. Crystallographic studies showed 1 to be fac-octahedral and 2 to be trigonal bipyramidal with the THF molecules in the axial positions.
