Dimeric and Trimeric Supramolecular Systems Formed by Donor‒Acceptor Interactions of ZnII, MnIII, and SnIV Porphyrin Complexes

The paper presents the methods of synthesis of dimeric and trimeric compounds formed by donor–acceptor interactions of Zn II , Mn III , and Sn IV porphyrin complexes. The structure of the porphyrin ensembles was determined by 1 H NMR spectroscopy. The extra coordination properties of the synthesized dimeric and trimeric supramolecular systems in relation to nitrogen-containing compounds were studied and the stability constants of the resulting porphyrin extra complexes were determined.
