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 thecondensation of citral and L-histidine. The ligand and its M(II) complexes were characterized basedon 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) complexesin which the M(II) centres are present in NNO coordination sphere. To evaluate the biological propertiesof the Schiff base ligand ( L) and its metal complexes, they were screened for their antibacterial andantifungal activities and the results indicate that the complexes exhibit the significant activity.
