Acridinium isophthalate

Z. Shaameri, N. Shan and W. Jones

Abstract: The crystal structure of the title complex, C₁₃H₁₀N⁺·C₈H₅O₄^-, confirmed the full proton transfer, i.e. protonation of the acridine N atom and deprotonation of one of the carboxylic acid groups, in the isophthalic (1,3-benzenedicarboxylic) acid. In the title complex, isophthalate anions are linked via strong O-HO bonds and weak C-HO bonds into infinite chains along the a axis of the crystal. The acridinium cations are attached to the anionic chains via strong hydrogen bonds involving the carboxylate groups of the isophthalate anion and the NH group of the acridinium cation.
