Studies on A Novel S-Triazine Based ONO Donar Heterocyclic Ligand and its Transition Metal(II) Complexes

A series of metal(II) complexes of a novel ONO donar type ligand 4,6-bis(antipyrin-4ylamino) -N-phenyl -2-amino-1,3,5-triazine with general formula ML.(NO3)2.H2O [ where M= Cu(II), Ni(II), Co(II) and Zn(II) ] have been synthesized. The structural features of the ligand and the metal complexes have been characterized by micro analytical data, magnetic susceptibility measurements, molar conductance, IR, UV-VIS, H 1 NMR spectral techniques. Cyclic voltammogram of copper(II) complex reveals that the redox process is irreversible one. The free ligand and their metal complexes have been screened for their in vitro biological activity against bacteria E.Coli, ,Pseudomonas aeruginosa, bacillus substilis and vibrio.sp and the fungi Candida albican by well diffusion method and reveal that the metal(II) complexes have increased activity than that of free ligand.
