“…The characteristic of azomethine (C¼N) is the strong absorption at 1633-1601 cm À1 for the complexes. These bands are characteristic for Schiff bases [23]. The carboxyl groups (COO À ) show two normal vibrations between 1594-1537 and 1393-1352 cm À1 .…”

“…Equatorial ligation has only a minor influence on the spectra [23,26]. The uranyl complexes show two absorptions, 1 and 2 , between 374 and 471 nm, assigned to charge transfer (LMCT) transitions.…”

“…This behavior shows there is moderate binding and a considerable affinity between the complex and DNA [11,23,34]. Probably the water molecules from the complex were expelled during this binding process.…”

Complexes of uranyl(VI) (U(VI)) with tridentate ligands derived from salicylaldehyde and aminoacids are reported, bis 2-((2-hydroxybenzylidene)amino)acetic acid U(VI), UO 2 (SalGly) 2 (1); tri (4), and tri aqua 2-((2-hydroxybenzylidene)amino)-4-(methylthio)butanoic acid U(VI) nitrate, [UO 2 (SalMet) (H 2 O) 3 ]NO 3 (5). The characterization of the complexes was performed by electrospray mass spectroscopy, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, fluorescence spectroscopy, and thermal analysis. The complexes are electrolytes (1 : 1) having a molar ratio M : L ¼ 1 : 1, except 1, which is a nonelectrolyte with a molar ratio M : L ¼ 1 : 2. The fluorescence intensity of the complexes is more intense than uncomplexed uranyl, except 1 and 5. High fluorescence of the uranyl SalAla complex (2) was used to assess complexes-DNA interaction based on fluorescence quenching assay. The interaction of 2 with DNA was assessed by measuring the relative fluorescence quenching of the complex when nucleic acids were added.
