Abstract
The complexes of two new ligands, 2‐acetylnaphtho[2,1‐b]furan oxime (L1) and 2‐benzoylnaphtho[2,1‐b]furan oxime (L2), with the metal ions Cu(II), Ni(II), Co(II), Cd(II), and Hg(II) have been synthesized and characterized on the basis of elemental analyses, conductance, magnetic susceptibility measurements, TGA, powder x‐ray diffraction, NMR, UV‐electronic, and IR spectral studies. Coordination of the ligand atoms to the metal ion was deduced by NMR and IR spectral data. Magnetic studies revealed the structures of the complexes. The stability of the complexes was studied by thermal analysis. Powder x‐ray diffraction studies of the complexes have shown that they are crystalline in nature. All the complexes, ligands and metal salts have been screened for antimicrobial, anthelmintic, and analgesic activities.
