Luminescence Studies of Tris(bis(trimethylsilyl)amido)terbium(III) and of its Adduct Complexes

Modern organolanthanoid chemistry relies almost entirely upon X-ray crystallography for the study of complex structure.[1,2] Unfortunately, solid-state and solution-phase structures of a given compound are not necessarily related. Since many organolanthanoid compounds have been proposed as homogeneous catalytic reagents,[3] the evaluation of their solution-phase structures represents an important problem. In particular, information on the perturbations of complex stucture caused by solvation phenomena and adduct formation are of virtal importance in understanding the chemistry of these materials, but this information is obviously not available from solid-state structural studies.
