Abstract
In the current study, of two azo dyes made from coumarin and procaine (T1) and coumarin and Sulfa guanidine (T2)were synthesized. The dyes were characterized by IR, CHN, 1H-NMR, 13C-NMR and MS spectroscopic techniques. .
To make azo metal(II) complexes, these novel legands were combined with acetate salts of copper(II) and nickel(II) in a 1:2 molar ratio.The metal to ligand ratio [M:L] in all complexes, according to analytical data, is (1:2).This ligand behaves as a bidentate chelating, according to spectral and analytical data.Thermo gravimetric (TGA) analysis was used to study the thermal behavior of these substances. These chemicals' thermal breakdown is a multi-stage process
