Synthesis of Copper(II) and Manganese(II) complexes using 2-hydroxybenzyl-(pyridine-2-carbo) iminohydrazone and 2-Furyl (pyridine-2-carbo) Iminohydrazone: Evaluation of their antimicrobial properties

Abstract

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. Antimicrobial studies have been performed for these compounds with different antimicrobial species.
