Luminescence spectroscopy studies were carried out on europium(III) complexation with HL = uracil, thymine (5-methyluracil), 6-chloromethyluracil, 5-hydroxymethyluracil and 6-methyluracil in acidic perchlorate solutions. In acidic medium the decrease of the hydration number with increasing the ligand excess indicates a consecutive complexation via metal - O4 coordination. The potentiometric method confirmed the possibility of coordination by N3 at higher pH for thymine, 6-chloromethyluracil and 6-methyluracil. The formation of hydroxo species has been ascertained for all the ligands.
