Abstract: Complexes with composition Ln2(β-diketonate)6 · (dmm) (Ln = Eu, Tb; dmm = 2,6-dtmethyl-morpholine; β-diketonate = 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanodionate (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 77 K. 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 C3v symmetry around the central ion.
