In the title compound, C5H9NO2·2C6H5NO3, the pyrrolidine ring of the pyrrolidinium-2-carboxyl-ate zwitterion adopts a twisted conformation on the -CH2-CH2- bond adjacent to the N atom. The mean plane of this pyrrolidine ring forms dihedral angles of 25.3 (3) and 32.1 (3)° with the two nitro-phenol rings. An intra-molecular N-H⋯O hydrogen bond occurs in the pyrrolidinium-2-carboxyl-ate mol-ecule. In the crystal, mol-ecules are linked via O-H⋯O and N-H⋯O hydrogen bonds, enclosing R (3) 2(8) ring m ...[more]
