    The palladium(II) complexes PdL1-3, bearing bi-dentated Schiff base ligands (L1-3) were synthesized and characterized by FT-IR, NMR and single crystal-XRD techniques, and the structural, spectroscopic and electronic properties were obtained using the B3LYP density functional method (DFT). The fabricated complexes were used as catalysts in the reduction of some organic pollutants (4-nitrophenol (4-NP), Rhodamine B (Rh B) and methylene blue (MB)) in water at an ambient temperature. The PdL3 complex was recorded as the best catalyst compared to the other complexes and the highest conversion rates were in the order of MB > RhB > 4-NP. Also, the antimicrobial and antifungal activities of all the compounds (ligands and complexes) and the cytotoxic effects on DU-145 and SH-SY5Y cells were investigated. The PdL1-3 complexes show cytotoxic effects, especially against the SH-SY5Y cells. All the synthesized com- pounds showed moderate antimicrobial and antifungal properties.

    Synthesis, catalytic, cytotoxic, and antibacterial properties of new Ru(II) and Pd(II) complexes bearing bidentate Schiff base ligand
    (Taylor and Francis Ltd., 2021) Selvi, Gizem; Özdemir, Fethi Ahmet; Aykutoğlu, Gürkan; Özdemir, Namık; Şerbetçi, Zafer; Dinçer, Muharrem; Dayan, Osman
    In the present study, new Ru(II) and Pd(II) complexes with sulfonated bidentate Schiff base ligand were synthesized and structurally characterized by NMR, FT-IR, MS spectroscopic methods. Additionally, the solid-state structure of the Schiff base ligand was determined with a single crystal-XRD technique. Then, the antibacterial properties and in vitro cytotoxicity of the synthesized compounds were investigated. Also, the catalytic activities of the Ru(II) and Pd(II) complexes were examined comparatively for the degradation of Eosin Yellow.
