The solid-state structures of the salts of two substituted tryptamines, namely N -isopropyl- N -methyltryptaminium (MiPT) fumarate {systematic name: [2-(1 H -indol-3-yl)ethyl](methyl)propan-2-ylazanium 3-carboxyprop-2-enoate}, C 14 H 21 N 2 + ·C 4 H 3 O 4 − , and 4-hydroxy- N -isopropyl- N -methyltryptaminium (4-HO-MiPT) fumarate monohydrate {systematic name: [2-(4-hydroxy-1 H...
The title compound (systematic name: bis{2-[4-(acetyloxy)-1 H -indol-3-yl]ethan-1-aminium} but-2-enedioate), 2C 14 H 19 N 2 O 2 + ·C 4 H 2 O 4 2− , has a single protonated psilacetin cation and one half of a fumarate dianion in the asymmetric unit. There are N—H...O hydrogen bonds between the ammonium H atoms and the fumarate O atoms, as well as N—H...O hydrogen bonds between the indole H atoms...
