| 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. |
