Abstract: Complexes with composition Ln(2)(beta-diketonate)(6) . (dmm) (Ln = Eu, Tb; dmm = 2,6-dimethylmorpholine; beta-diketonate = 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanodiate (tta); 4,4,4-trifluoro-1-phenyl-1,3-butanodionate (tfpb) and 1,1, 1-trifluoro-1,4-pentanedionate (tfa)) have been synthesized. The adducts were characterized by microanalyses, IR spectra and emission spectra at room temperature and at 77K. The spectra of europium complexes indicate the oligomeric at least dimeric, nature of the compounds, since the bands are broad. The number of peaks in all cases was interpreted as C-3v symmetry around the central.
