چکیده
The title compound, C(16)H(17)NO(2), crystallizes with three crystallographically independent zwitterionic mol-ecules in the asymmetric unit which differ significantly in the orientations of the propyl side chains. The dihedral angles between the two benzene rings in the three mol-ecules are 6.17 (7), 6.75 (7) and 23.67 (7)°, respectively. In each independent mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, each independent mol-ecule exists as part of an O-H⋯O hydrogen-bonded centrosymmetric R(2) (2)(10) dimer.

The title mol-ecule, C(13)H(9)N(3)O(6), consists of a 2-hydr-oxy-5-nitro-phenyl-iminio group and a 4-nitro-phenolate group bonded to a methyl-ene C atom with both of the planar six-membered rings nearly in the plane of the mol-ecule [dihedral angle = 1.3 (4)°]. Each of the nitro O atoms is twisted slightly out of the plane of the mol-ecule. The amine group forms an intra-molecular hydrogen bond...
