Abstract: A new ligand N-Benzothiazol-2-yl-N’- Naphthalen-1-yl-Ethane-1,2-diamine (BTNEA) was synthesized from the reaction of 2-mercaptobenzothiazole with N-naphthalen-1-yl-ethane-1,2-diamine in absolute ethanol as reaction medium. Its complexes were prepared by reacting the ligand with metals salts of (Co(II), Cu(II), Zn(II) ,Cd(II) and Hg(II)). The structures of ligand and its complexes were confirmed by melting point, elemental analysis, FT-IR, 1H-NMR and UV/visible spectra. In addition, to these characterization methods molar ratio (M:L), magnetic measurements, molar conductivity were used to characterize synthesized complexes. Flame atomic absorption spectroscopy was used to determine metal content (M%) of these complexes. The structures of the (Co(II), Cu(II)) complexes suggested as octahedral geometry while other complexes as tetrahedral geometry.
