Abstract
Abstract
In the present study, two new azo dyes from 4-amino-N-(4-methyl-2- pyrimidinyl(benzenesulfonamide) with acetylacetone( L1) and benzoyl acetone(L2) were synthesized. The characterization of dyes has been described by IR,C.H.N,1H-NMR, and TGA. The reaction of these new dyes with acetate salts of copper(II) and nickel(II) in molar ratios of 1:2 was carried out to produce azo metal(II) complexes. Theanalytical data show that the metal to ligand ratio [M:L] in all complexes is (1:2). The spectral and analytical data revealed that this ligand behaves as a bidentate chelating. The thermal behavior of these compounds was investigated based on thermogravimetric (TGA) analyse. Thermal decomposition of these compounds is multi-stage processes.
