'Foxtrot' fumarate: a water-soluble salt of N, N-di-allyl-5-methoxytryptamine (5-MeO-DALT)

The title compound, bis-(N,N-diallyl-5-meth-oxy-tryptammonium) (5-MeO-DALT) fumarate (systematic name: bis-{N-[2-(5-meth-oxy-1H-indol-3-yl)eth-yl]- N-(prop-2-en-1-yl)prop-2-en-1-aminium} (E)-but-2-enedioate), 2C₁₇H₂₃N₂O⁺·C₄H₂O₄ ^2-, has a single tryptammonium cation and half of a fumarate dianion in the asymmetric unit. The tryptammonium and fumarate ions are held together in one-dimensional chains by a series of N-H⋯O hydrogen bonds. These chains are combinations of R ⁴ ₄(22) rings, and C ² ₂(14) and C ⁴ ₄(28) parallel chains along [111].
