The synthesized complexes exhibit variable degree of antibacterial activity. The complexes have been characterized by elemental analysis, IR, [1H]-NMR spectroscopy and magnetic studies. The spectroscopic studies suggest a bidentate behavior of the ligand via pyrimidine-N and imine-N donor atoms with the metal (0). | | Keywords : | | |
