RESUMO
In the zwitterionic title compound, C(18)H(16)N(2)O(4), the dihedral angle between the planes of the benzene and indole rings is 26.38â (10)°. An intra-molecular N-Hâ¯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through N-Hâ¯O, O-Hâ¯O and C-Hâ¯O hydrogen bonds into infinite chains propagating in [010].

RESUMO
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 39.20â (8)°. An intra-molecular N-Hâ¯O hydrogen bond generates an S(6) ring motif. In the crystal, inter-molecular hy-droxy and water O-Hâ¯O(carboxyl-ate) and N(+)-Hâ¯O(carboxyl-ate) and indole N-Hâ¯O(water) hydrogen bonds give a three-dimensional structure.
