A Schiff baseL[2-thiophenecarboxylic acid, 2-(2-pyridinylmethylene)hydrazide] with its lanthanide metal complexeswas synthesized. These complexes were characterized by elemental analysis, molar conductivity measurements, spectral analysis (NMR, FT-IR, and UV-Vis), luminescence and thermal gravimetric analysis. The Schiff base ligandwas a tridentate chelate and coordinates to the central lanthanide ion with 1:2 metal:ligand ratio. The conductivity data showeda1:1 electrolytic nature with a general formula [LnL2(NO3)2]NO3. The luminescence emission properties for Sm,Tb, and Eu complexeswere observed and showedthat the ligandL couldabsorb and transfer energy to Sm(III), Tb(III) and Eu(III)ions. The complexes possesseda good antibacterial activity against different bacterial strains. In addition,the scavenging activity of the Ln(III) complexes on DPPHwas concentration dependant and the complexeswere significantly more efficient in quenching DPPH than the free Schiff base ligand.
