Abstract Molecules of the title compound, C14H8N2O5, are linked by a hydroxy–amide O—H O hydrogen bond into a linear chain. The hydroxy group is disordered over two positions of the benzene ring in an approximate 0.57:0.43 ratio.Related literature Experimental Crystal data

Comment The title compound (Fig. 1) was synthesized for studies on intramolecular
general base (IGB) and intramolecular general acid (IGA) catalysis in the
hydrolysis of N-substitutedphthalimide (Sim et al., 2006;
2007).
Experimental 4-Nitrophthalic anhydride (5.0 g, 26 mmol) and o-hydroxyaniline (3.4 g,
31 mmol) were heated in glacial acetic acid (15 mol) for 4 h at 393–401 K.
The reaction was shown to be complete by thin layer chromatography. The
mixture was poured into water. The yellow solid was collected in 90% yield;
purification was effected by recrystallization from chloroform.
Refinement Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 Å) and
were included in the refinement in the riding model approximation, with
U(H) set to 1.2Ueq(C). The hydroxy group is disordered over
two positions on the phenylene ring; the disorder refined to a 0.571 (1):429 (1)
ratio. Figures
