Synthesis, Spectral and Thermal Studies of New Azo Dyes Complexes Derived From 3-tert-butyl-4-hydroxyanisol

Abstract

    New azo dyes ligand of substituted amines para-toluidin and 3-aminophenol with 3-tert-butyl-4-hydroxyanisol and their complexes with Ni(II) and Cu(II) were synthesized and characterized using (¹HNMR, ¹³CNMR, mass spectrometry, FT-IR, Uv–Vis, molar conductance, elemental analysis, magnetic moment and thermogravimetric analysis). The spectral,studies and analytical,data revealed that the azo dyes,ligands act as bidentate ligands via deprotonated OH and nitrogen atom of the azo group. The low molar conductance data detected that all the metal complexes were non-electrolytic in nature, as well as showed that the reaction ratio was 1:2 metal:ligand and had paramagnetic properties for all metal complexes and had an octahedral geometrical shape for Ni complexes and tetrahedral for Cu complexes. Thermal,analysis,studies showed the decomposition,of the complexesain two to three steps with the weight loss of hydratedawater in the first,decomposition,stepafollowed by the coordinated,water and ligand molecules.
