TRANSITION METAL COMPLEXES WITH LIGAND CONTAINING THIOAMIDE MOIETY: SYNTHESIS, CHARACTERIZATION AND ANTIBACTERIAL ACTIVITIES

A new series oftransition metal complexes of Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) with the ligand 3-thionicotinoylaminodibenzofuran (L) were synthesized. The complexes were characterized by elemental analyses, metal content, spectroscopic methods (IR, UV-vis, NMR and EPR), conductivity and susc...
