Abstract
A new series of [M(L)Y]X·nH2O (M = Co(II) and Cu(II), where Y = H2O, X= NO3
–, n = 3), M = Ni(II),
where Y = H2O, X = NO3
–, n = 2) complexes with new Schiff base ligand (L) were synthesized by the
condensation of citral and L-histidine. The ligand and its M(II) complexes were characterized based
on elemental analysis, spectroscopic studies like FT-IR, electronic, 1H NMR, 13C NMR, ESR data,
also accompanied with thermal studies, magnetic susceptibility and molar conductance measurements.
In the light of these results, distorted square planar geometry were proposed for the M(II) complexes
in which the M(II) centres are present in NNO coordination sphere. To evaluate the biological properties
of the Schiff base ligand ( L) and its metal complexes, they were screened for their antibacterial and
antifungal activities and the results indicate that the complexes exhibit the significant activity.
