Hydrazone as complexing agent: Synthesis, structural characterization and biological studies of some complexes
摘要:
This paper deals with the synthesis, magnetic, spectral, thermal, and biological studies of Ti(III), VO(IV), Cr(III), Mn(III), Fe(III), and Zr(IV) complexes with chelating hydrazone derived from 2-hydroxy-5-methylacetophenone and furoic acid hydrazide. The acid hydrazone synthesized is 2-hydroxy-5-methylace-tophenone-furoylhydrazone. The ligand has been characterized on the basis of IR and H-1 NMR spectra. The presence of water molecules and thermal stabilities of the complexes are also reported. Solid-state electrical conductivity was measured over a 313-410-K temperature range, and the compounds show semiconducting behavior. The new complexes have been screened for their antibacterial and antifungal activity, and they show higher activity than free ligands.
