Crystal structure of N-(3-hydroxyphenyl)succinimide

In the title compound, C10H9NO3, the dihedral angle between the benzene and pyrrolidine rings is 53.9 (1)°. In the crystal, molecules are linked through strong O—H⋯O hydrogen bonds into zigzag C(8) chains running along [010]. The chains are linked by C—H⋯π interactions forming sheets lying parallel to (100).


S1. Introduction
As a part of a study on the effect of ring and side-chain substitutions on N-(Aryl)-succinimides (Saraswathi et al., 2010(Saraswathi et al., ,2011, the title compound has been synthesized and we report herein on its crystal structure.

S2.1. Synthesis and crystallization
The title compound was prepared according to the reported procedure (Saraswathi et al., 2010(Saraswathi et al., ,2011. Colourless prisms of the title compound were obtained by slow evaporation of an aqueous methanolic solution at room temperature.

S2.2. Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2. The hydroxyl H atom was located in a difference Fourier map and freely refined. The C-bound H atoms were positioned with idealized geometry and treated as riding atoms: C-H = 0.93-0.97 Å with U iso (H) = 1.2U eq (C).
In the crystal, molecules are linked through strong O-H···O hydrogen bonds into zigzag C (8)

Special details
Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > 2σ(F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
