Synthesis and Thermal Studies of Some Metal azo Complexes Derived from Hydroxy coumarin
Keywords:azo Complexes , Synthesis and Thermal Studies
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
