(Received 4 April 2008; accepted 17 April 2008; online 23 April 2008)

The title compound, C15H9Cl2NO3, crystallizes as an inversion twin, the ratio of the twin components being 0.43 (13):0.57 (13). The isoindoline group is planar and inclined by 77.63 (3)° to the aromatic ring substituent. The crystal structure is stabilized by aromatic ππ stacking inter­actions involving the benzene rings of adjacent isoindoline groups, with a centroid–centroid distance of 3.664 (7) Å and an inter­planar separation of 3.409 Å.

Comment top

The present work is part of a structural study of derivatives of N-arylphthalimides (Abdel-Hafez, 2004; Chapman et al., 1979; Hall et al., 1983; Hall et al., 1987; Sena et al., 2007; Srivastava et al., 2001). We report here the crystal structure of 5,6-dichloro-2-(3-methoxyphenyl)isoindoline-1,3-dione.

The molecule of the title compound consist of a 5,6-dichlorophthalimide unit connected to a m-methoxyphenyl group through the nitrogen atom (Fig. 1). The isoindoline ring (atoms N1/C1–C8) is almost planar, the largest deviation from the mean plane being 0.051 (3) Å for atom C5. The dihedral angle between the methoxyphenyl ring and the mean plane of the isoindoline group is 77.63 (3)°. The crystal packing is stabilized by aromatic π···π stacking interactions (Fig. 2) occurring between the aromatic rings of isoindoline groups at (x, y, z) and (-1/2+x; 3/2 - y; 1-z), with a centroid-centroid distance of 3.664 (7) Å and a plane-plane separations of 3.409 Å.

Experimental top

A mixture of 4,5-dichlorophthalic acid (1.175 g, 0.005 mol) and 2-aminophenol (0.545 g, 0.02 mol) in DMF (1.5 ml) was heated at boiling temperature for 15 min, then ethanol (95%, 50 ml) was added. Crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation of this mixture at room temperature (yield 80%; mp. 546–548 K).

Refinement top

H atoms were positioned geometrically, with C—H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms. The rather high Rint value is ascribed to the poor nature of the available crystals.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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.
