A new ligands l,l,2,2-tetrakis-(benzothiazolethio) ethylene (Li) and mercaptobenzothiazole potassium (L2) had been synthesized, investigated and used in the preparation of Mn*2, Co+2, Ni*2 and Cu+2 complexes. Also the reaction of the above complexes with 1,10-phenanthroline has been reported. The complexes and adducts were characterized using IR and UV-visible spectroscopy, atomic absorption molar conductivity and magnetic moments measurements. Electronic spectra and magnetic measurement showed that some of the complexes have tetrahedral geometry, the other complexes and the adducts have an octahedral geometry.
