摘要
Direct experimental confirmation of the formation of ion-molecular associates of (5,10,15,20-tetraphenyl-21H,23H-porphinato)silver(II) (AgTPP) with solvent protons in CF3COOH is obtained by means of 1H NMR spectroscopy. Their structure and spectral properties, as well as the kinetics of dissociation on metal-nitrogen bonds, depending on the concentration of CF3COOH (89-100%) and temperature (298-328 K), are studied It is shown that AgTPP acts as a C-base during the formation of H+ associates, the coordination centers of which have a high stability.
