Transition metal complexes of Cr(III), Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) metal
ions with general stoichiometry [ML2.2H2O] and [ML3], where M= Mn(II), Cr(III), Fe(II), Co(II), Ni(II) and Cu(II), L= Schiff base derived
from the condensation of 2-amino-4(4’-phenyl/methylphenyl)-5-methyl-thiazole with
4-acetyl-1(3-chloro phenyl)-3-methyl-2-pyrazoline-5-ones, have been synthesized and
structurally characterized by elemental analysis, molar conductance measurements,
magnetic susceptibility measurements and spectral techniques like IR, UV,1H NMR,13C NMR and Mass Spectra. All the complexes were found to be octahedral geometry. The
ligand and its complexes have been screened for their antifungal and antibacterial
activities against three fungi,i.e. Alternaria brassicae, Aspergillus nigerandFesarium oxysporumand two bacteria,i.e. Xanthomonas compestrisandPseudomonas aeruginosa.
