Popis:	The compounds of Eu(III) with nicotinic acid and enrofloxacin are synthesized. Their composition and structure are proved by the data of elemental analysis, IR and luminescence spectroscopy, powder and single crystal X-ray diffraction. By single crystal X-ray diffraction, the structure of the compound of Eu with nicotinic acid is identified as a centrosymmetric dimer with 4 carboxylate bridges of the composition Eu2(C6H4NO2)6·4H2O. The Stark structure of the 5 D 0-7 F j transitions in the mixed-ligand compounds of Eu(III) with nicotinic acid and enrofloxacin is determined. The bands of IR spectra are assigned; the conclusion about the bidentate coordination of ligands is made.
