dc.description.abstract Atrazine (ATA)− a well known herbicide has been derivatized into 2-hydroxylamino-4- ethylamino-6-isopropylamino-s-triazine (HAATZ). Simazine (SMZ) was derivatized into 2-hydrazino-4,6-bis(ethylamino)-s-triazine (HSMZ). The physical and spectral data confirmed the formation of HAATA and HSMZ. Amitrole (ATA) has been derivatized into 3-(N-Salicylidene) aminotriazole (NSATA). Suspension of NSATA in methanol was used to synthesize metal complexes of Co(II), Ni(II) and Cu(II). They have been characterized on the basis of analytical, magnetic susceptibility, coductamce, IR, NMR, UV-VIS spectral studies. The conductivity measurement studies show the complexes are non electrolytes and no chloride in the complexes. Magnetic susceptibility measurement indicated that Co(II) complex is paramagnetic while Ni(II) and Cu(II) are diamagnetic. The Schiff base, NSATA behaves as neutral bidentate ON donor, with phenolic oxygen and exocyclic nitrogen acting as metal binding sites. An octahedral geometry for Co(II) complex and square planar geometry for Ni(II) and Cu(II) complexes are proposed.
