Schiff condensation of 2,6-diformyl 4-methylphenol with semicarbazide hydrochloride in 1:2 molar ratio produces the bis(semicarbazone) ligand, herein called H3L. A comprehensive spectroscopic analysis of the compound was performed by 1H and 13C NMR, FTIR and electronic spectroscopies. Assignments to the UV–vis spectrum of H3L were supported by semi-empirical quantum mechanics ZINDO/S calculations...
