The solution of succinic anhydride (0.02 mole) in toluene (25 ml) was treated dropwise with the solution of 3-methylaniline (0.02 mole) also in toluene (20 ml) with constant stirring. The resulting mixture was stirred for one hour and set aside for an additional hour at room temperature for the completion of reaction. The mixture was then treated with dilute hydrochloric acid to remove the unreacted 3-methylaniline. The resultant solid N-(3-methylphenyl)succinamic acid was filtered under suction and washed thoroughly with water to remove the unreacted succinic anhydride and succinic acid. It was recrystallized to constant melting point from ethanol.
N-(3-methylphenyl)succinamic acid was heated for 2 h and then allowed to cool slowly to room temperature to get the compound, N-(3-methylphenyl)succinimide. The purity of the compound was checked and characterized by its infrared spectra.
Rod like colourless single crystals of the compound used in X-ray diffraction studies were grown in ethanolic solution by a slow evaporation at room temperature.
The H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.97 Å. Isotropic displacement parameters for the H atoms were set equal to 1.2 Ueq (parent atom).
As a part of studying the effect of ring and side chain substitutions on the structures of biologically significant compounds (Saraswathi et al., 2010a,b), the
of N,N-(3-methylphenyl)succinimide has been determined (Fig.1). In the structure, the molecule is non-planar with the benzene and pyrrolidine rings tilted by 52.5 (1)° with respect to one another, compared to the values of 57.3 (1)° in N,N-(4-methylphenyl)succinimide (Saraswathi et al., 2010a) and 67.7 (1)° jn N,N- (2,3-dimethylphenyl)succinimide (Saraswathi et al., 2010b).The torsional angles of the groups, C2 - C1 - N1 - C7, C6 - C1 - N1 - C7, C2 - C1 - N1 - C10 and C6 - C1 - N1 - C10 in the molecule are 52.6 (2), -127.0 (2), -123.4 (2) and 57.0 (2)°, respectively, while the torsional angles of the groups, O1 - C7 - N1 - C1, C8 - C7 - N1 - C1, O2 - C10 - N1 - C1 and C9 - C10 - N1 - C1 are 7.7 (3), -171.5 (2), -2.1 (3) and -178.6 (2)°, respectively.
The packing of molecules into layered row like chains along b-axis is shown in Fig.2.

Experimental. CrysAlis RED (Oxford Diffraction, 2009) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm. |
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As a part of studying the effect of ring and side chain substitutions on the structures of biologically significant compounds (Saraswathi et al., 2010a,b), the crystal structure of N,N-(3-methylphenyl)succinimide has been determined (Fig.1). In the structure, the molecule is non-planar with the benzene and pyrrolidine rings tilted by 52.5 (1)° with respect to one another, compared to the values of 57.3 (1)° in N,N-(4-methylphenyl)succinimide (Saraswathi et al., 2010a) and 67.7 (1)° jn N,N- (2,3-dimethylphenyl)succinimide (Saraswathi et al., 2010b).
The torsional angles of the groups, C2 - C1 - N1 - C7, C6 - C1 - N1 - C7, C2 - C1 - N1 - C10 and C6 - C1 - N1 - C10 in the molecule are 52.6 (2), -127.0 (2), -123.4 (2) and 57.0 (2)°, respectively, while the torsional angles of the groups, O1 - C7 - N1 - C1, C8 - C7 - N1 - C1, O2 - C10 - N1 - C1 and C9 - C10 - N1 - C1 are 7.7 (3), -171.5 (2), -2.1 (3) and -178.6 (2)°, respectively.
The packing of molecules into layered row like chains along b-axis is shown in Fig.2.
