Abstract:	Neutral EuL₃Phen] complexes were synthesized by the reaction of EuCl₃ with heterocyclic diketones-1-(1,5-dimethyl-1H-pyrazol-4-yl)-4,4,4-trifluoro-1,3-butanedione and 4,4,5,5,6,6,6-heptafluoro-1-(1-methyl-1H-pyrazol-4-yl)-1,3-hexanedione—and 1,10-phenanthroline (Phen) in an aqueous alcohol solution in the presence of NaOH. The reaction of GdCl₃ with the same diketones under analogous conditions, but without adding 1,10-phenanthroline, yielded GdL₃(H₂O)₂] complexes. The composition of the complexes was determined by elemental analysis, and their optical and luminescent properties were examined.
