I.6-hydroxy-4metheyl-5-phenyl azo coumarin have been prepared and characterized by elemental analysis, infrared (IR), proton nuclear magnetic resonance (1H NMR) and Mass spectra. The important infrared (IR) spectral bands corresponding to the active groups in the ligand and the solid complexes under investigation were studied. Also the important fragments in the ligand and the complexes were done using mass spectra and the main peaks were corresponding to the molecular weights of the ligand and complexes. The solid complexes have been synthesized and studied by elemental and as well as by IR, 1H NMR, mass spectra, molar conductance,. All of the prepared solid complexes behave as non-electrolytes in chloroform.en-USSynthesis; Transition metal complexes; Spectroscopic; molar Conductance.Article273273
