چکیده
In the title compound, C(13)H(13)NO(4), the dihedral angle between the nine-membered phthalimino ring system and the carb-oxy-lic acid group is 67.15 (9)°. An intra-molecular C-H⋯O close contact, which forms an S(6) ring, may help to establish the mol-ecular conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, thereby forming C(7) chains propagating in [010].

The title compound, C(13)H(13)NO(4)S, the 1,3-dioxoisoindolin-2-yl unit is planar (r.m.s. deviation 0.0192 Å) and is oriented at a dihedral angle of 79.14 (18)° to the carboxyl-ate group. An intra-molecular C-H⋯O hydrogen bond leads to the formation of a planar (r.m.s. deviation 0.0419 Å)R(5) ring motif. In the crystal, mol-ecules are connected through O-H⋯O and C-H⋯O hydrogen bonds with R(2) (...

The title salt, C3H5N2 (+)·C10H6NO4 (-), was obtained during a study of the co-crystallization of N'-[bis-(1H-imidazol-1-yl)methyl-ene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å]. In the crystal, cations and anions are linked via classical N-H⋯...
