Synthesis and characterization of Pd(II) and Ni(II) complexes of schiff bases and catalytic activity of Pd(II) complexes / Amalina Mohd Tajuddin, Hadariah Bahron and Shahrul Nizam Ahmad
Six new Pd(II) and Ni(II) metal complexes of N, O-bidentate (LI, L2) and ONNO-tetradentate (L3) Schiff base ligands have been synthesized. The compounds were characterized via various physicochemical and spectroscopic techniques namely elemental analysis (CHN), FT-IR, IHand 13C NMR as well as magnet...
