ABSTRACT

Some Tetra dentate Schiff-base derived from 4-carboxaldehyde-3-methyl-1-phenyl-2- pyrazoline-5-one with meta phenelyne diamine. Form a stable complex with transition metal ions such as VO (III), Cr (II), Mn (II) and Fe (II) in ehanol. Tetradental Schiff base have been synthesized and characterized b using UV, IR, 1H & 13C-NMR spectral studies. The biological activities of the all metal complexes were measured against bacteria, yeast and fungi.
