Transition metal complexes derived from ethylacetoacetate- N-anilino hydrazone

ABSTRACT

The hydrazone of beta-diketone and their complexes are used as antituberculous agents [1], furthermore some hydrazones are used as analytical reagents[2, 3]. Co[II] and Cu[II] complexes with benzoyl and salicyloyl hydrazones derived from beta diketones have been prepared and characterized[4]. Mixed -ligand complexes based on beta-diketones of rare earth elements as well as diazo coupling[5] of Cr[III], Ni[II], Pd[II] and Cu[II] chelates of benzoylacetone and dibenzoyl methane[6-9] with phenylhydrazoniurn chloride were studied. Transition metal complexes of beta-diketone hydrazone ligands have been synthesized and characterized by elemental analyses, UV/Vis and IR spectroscopy, conductance determinations in DMF and magnetic susceptibility measurements [10]. beta-diketone phenylhydrazones of substituted 3-aryldiene-2, 4-pentanediones with phenylhydrazine have been synthesized and characterized by elemental analyses, IR, magnetic susceptibility and thermogravimetry[11]. In this paper the synthesis and characterization of transition metal complexes of ethylacetoacetate-N-anilinohydrazone derived from metal acetate in [11] [ML] ratio were studied
