Abstract
The solid-state structure of the title salt/adduct (systemic name: bis{[2-(4-acetyloxy-1H-indol-3-yl)ethyl](ethyl)propylazanium} but-2-enedioate–(E)-butenedioic acid (1/1)), 2C17H25N2O2
+·C4H2O4
2−·C4H4O4, was determined by single-crystal X-ray diffraction. The asymmetric unit consists of a singly protonated tryptammonium cation, one half of a fumarate dianion and one half of a fumaric acid molecule. In the crystal, the ions and molecules are linked together in infinite chains propagating along [001] through a series of N—H...O and O—H...O hydrogen bonds.
