Figure 3
The hydrogen bonding of a hydro­fumarate ion in the structure of N-ethyl-N-propyl­tryptammonium hydro­fumarate, with hydrogen bonds shown as dashed lines. Only one component of the disorder is shown, and hydrogen atoms not involved in hydrogen bonding are omitted for clarity. Symmetry codes: (i) 1 + x, y, z; (iv) −1 + x, y, z; (v) 2 − x, −[{1\over 2}] + y, 1 − z.
