(E)-2-[(2,4-Dihy­droxy­benzyl­idene)aza­nium­yl]-3-(1H-indol-3-yl)propano­ate monohydrate

In the zwitterionic title compound, C(18)H(16)N(2)O(4)·H(2)O, the dihedral angle between the planes of the benzene and indole rings is 39.20 (8)°. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inter­molecular hy­droxy and water O—H⋯O(carboxyl­ate) and N(+)—H⋯O(...

Sumario:In the zwitterionic title compound, C(18)H(16)N(2)O(4)·H(2)O, the dihedral angle between the planes of the benzene and indole rings is 39.20 (8)°. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inter­molecular hy­droxy and water O—H⋯O(carboxyl­ate) and N(+)—H⋯O(carboxyl­ate) and indole N—H⋯O(water) hydrogen bonds give a three-dimensional structure.
