Bis(4-acetoxy-N-ethyl-N-n-propyltryptammonium) fumarate–fumaric acid (1/1)

Abstract

The solid-state structure of the title salt/adduct (systemic name: bis{[2-(4-acetyloxy-1 H -indol-3-yl)ethyl](ethyl)propylazanium} but-2-enedioate–( E )-butenedioic acid (1/1)), 2C 17 H 25 N 2 O 2 + ·C 4 H 2 O 4 2− ·C 4 H 4 O 4 , 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.
