Popis: The acid-base interactions of tetrapyrazinoporphyrazine erbium(III) and lutetium(III) complexes in the media based on acetic and trifluoroacetic acids were investigated. The quantitative characteristics of equilibria between the acid-base forms were revealed. The structure of the acid forms was suggested. The reaction of solvoprotolytic dissociation of the octaphenyltetrapyrazinoporphyrazine lutetium(III) complex in CH3COOH-H2SO4 medium was studied and a scheme of the reaction mechanism was proposed.
