Abstract
A series of mononuclear complexes of the type, [MLCl2] [M = CoII, NiII, CuII, and ZnII] with a pyrimidene-type ligand, which was synthesized by the reaction of 2-furaldehyde and 1, 8-diaminonaphthalene, was obtained. The ligand and its complexes were characterized by elemental analysis, IR, NMR, EPR, and UV/Vis spectroscopy, ESI-mass spectrometry, magnetic susceptibility, molar conductivity, and thermogravimetric analyses. On the basis of UV/Vis spectroscopic and magnetic susceptibility data, an octahedral arrangement was assigned around all metal ions. The low molar conductivity data for all the complexes show their non-electrolytic nature. The thermal behavior of the complexes was studied by TGA analyses. The electrochemical study carried out on the CuII complex exhibits a quasi reversible redox process. The ligand and its complexes showed potential antioxidant and antimicrobial activities.
