Structure and stability of H+ associates of (5,10,15,20-tetraphenylporphinato)silver(II) in trifluoroacetic acid

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.
