The effort summarized preparation of metal chelates containing 4-carboxaldehyde-2-pyrazolin-5-one Schiff bases as ligand. Structural and spectroscopic properties of Schiff bases as well as metal chelates were studied on the basis of NMR (13C) spectra, IR spectrum and elemental analyses. All metal chelates further investigated by means of thermogravimetry, electronic spectra and magnetic measurements. TGA along with magnetic study support the geometry of metal chelates. Antimicrobial screening of Schiff bases and its metal chelates suggest that all the synthesized ligands and their metal...

The attempt summarized preparation of 4-carboxaldehyde-1-phenyl-3methyl-2-pyrazolin-5-one and their Schiff bases with p-phenylenediamine and benzidine. Structural and spectroscopic properties of neutral bidentate ligands were studied on the basis of mass spectra, NMR (1H and 13C) spectra, FT-IR spectrum and elemental analyses. Mass spectral data confirm the structure of ligands as indicated by the molecular ion peak (M+) corresponding to their molecular weight. Also the different metal complexes were synthesized using Schiff bases. Furthermore, the conductivity, magnetic, electronic spectral...
