Synthesis, Characterization and Antimicrobial Studies of Mn(II), Fe(III) and Co(II) Complexes of 2-cis-3,7-Dimethyl-2,6-Octadiene-1-Semicarbazone

Abstract

Complexes of Mn(II), Fe(IIl) and Co(II) with 2-cis-3,7-dimethyl-
2,6-octadiene-1-semicarbazone fonned by condensation of semicarbazone
hydrochloride and 2-cis-3,7-dimethyl-2,6-octadiene-1-al
have been synthesized and their physico-chemical properties have
been investigated by elemental analysis, magnetic measurements,
molar conductance, electronic spectroscopy and infrared spectroscopy.
The ligand was found to be bidentate chelating agent for the
metal ions. All these complexes have been tested in vitro for their
antimicrobial activity against bacteria Staphylococcus aureus (gram
postitive) and Escherichia coli (gram negative) and fungi Candida
albicans and Aspergillus niger.
