Abstract

The new series complexes of 2, 2’-{1,1'-( ferrocen-2,4-dien-1-yl) - 2,2'-diylbis[(e) methylylidene (e) azanylylidene]}dibenzoicacid have been prepared and characterized on the basis of elemental analysis, infrared, mass spectra, electronic spectra, thermal analysis, magnetic moment, conductivity, X-ray powder diffraction and antimicrobial activity. From the analysis data the complexes are 1:1 metal: ligand ratio with general formulae is [ML.2H2O]. The prepared complexes are non-electrolytic nature. The magnetic moment values, indicates that the complexes exhibited paramagnetic as well as diamagnetic in nature. The coordination behavior of the metal ions takes place through –HC=N- and -COOH groups of acid. The electronic spectral data shows that, complexes are covalent in nature, octahedral with co-ordination number six. The thermal studies indicate that, loss of ligand with increasing temperature. The prepared metal complexes are screened for their antibacterial activity against some Gram positive and Gram –ve bacterial species. The Antimicrobial activity data show the Pt metal ion complexes are more active as compare to other metal ions.

Keywords: Infrared, Mass Spectra, Electronic Spectra, Thermal Analysis, Conductivity and Antimicrobial Activity.
