The crystal structure of baeocystin

The title compound, baeocystin or 4-phosphor-yloxy-N-methyl-tryptamine {systematic name: 3-[2-(methylazaniumyl)ethyl]-1H-indol-4-yl hydrogen phosphate}, C11H15N2O4P, has a single zwitterionic molecule in the asymmetric unit. The molecule has an intra-molecular N-H⋯O hydrogen bond between the ammonium cation and the hydro-phosphate anion. In the crystal, the molecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.
