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

Three new coordination complexes [cu(hpbh)2]cl2 (1),[cu(fpfh)2]cl2 (2),and [mn(hpbh)2] cl 2 (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 like 1h and 13c 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. © 2013 jagvir singh et al.
