Synthesis and Spectral Studies of Copper (II) and Manganese (II) Complexes Using 2-Hydroxybenzyl-(pyridine-2-carbo)Iminohydrazone and 2-Furyl(pyridine-2-carbo)Iminohydrazone: Evaluation of Their Magnetic, and Antimicrobial Properties

[摘要] Three new coordination complexes [Cu(HPBH)2]Cl2(1), [Cu(FPFH)2]Cl2(2), and [Mn(HPBH)2] Cl2(3) (where HPBH=2-Hydroxybenzyl(pyridine-2-carbo)iminohydrazone, and FPFH=2-furyl(pyridine-2-carbo)iminohydrazone) have been synthesized using two different tridentate hydrazones ligand. The ligands were prepared by condensation of Pyridine-2-acetylchloride, 2-Hydroxybenzaldehyde and Furan-2-carbaldehyde with hydrazine, respectively, in spite of varying the carbonyl functionality attached to the pyridine moiety present in the hydrazones ligand. In both the Schiff bases, we obtained three mononuclear complexes 1, 2, and 3 which were clearly characterized from physicochemical studies. Spectroscopic investigations like1H and13C NMR, mass spectrometric, FTIR, and UV/Vis have been carried out for new compounds. For complexes 2 cyclic voltammetry, magnetic and EPR properties have also been recorded. Antimicrobial studies have also been performed for these compounds with different antimicrobial species.
