The present work focused on synthesis of triazine and their metal complexes. Its characterisation and anti-microbial activity were studied. Widely scope in co-ordination, medicinal chemistry. Bidentate chelate complex of ML2 type have been synthesized from triazine based ligand 4-amino-1-(naphthalene-1-yl)-1,6-dihydro-1,2,4-triazine-5(4H)- one. Their spectral analysis of chelates were study. Various synthetic metal of complexes of triazine are prepared and evaluated for its biological activity. Structures of the products have been deduced from their elemental analysis and spectral data such as 1 H-NMR have studied for determination of structure of its molecule, X- ray diffraction which provide information about the arrangement of crystal and Fourier transform infrared spectroscopy has been used to detect functional group present the compound). Select new synthesized compounds were screened as antimicrobial activity against Escherichia coil, proteus mirabilis, staphylococcus aureas, and P. aeruginosa has been carried out and compared with standard one.
