Electron donor–electron acceptor complexes of carbonyldi-imidazoles and thiocarbonyldi-imidazoles with iodine. Effect of solvent polarity
Abstract
The formation of charge-transfer complexes between carbonyl and thiocarbonyldi-imidazole with iodine has been investigated spectrophotometrically. The thermodynamic functions of formation, resonance energy, dipole moment and ionic character of the charge-transfer complex were calculated. The ionization potential of the donor was calculated from the charge-transfer results. The study has been conducted in different solvents and the results were analysed statistically.
