A mixture of 4,5,6,7-tetrachloroisobenzofuran-1,3-dione (0.01 mol) and 2-nitrobenzenamine (0.01 mol) in acetic acid (10 ml) was refluxed for 1 h. After cooling, filtration and drying, the title compound was obtained: 10 mg was dissolved in 15 ml acetone, and the solution was kept at room temperature for 5 d. Natural evaporation gave colourless blocks of (I).
The H atoms were initially located from difference maps, relocated in idealized locations (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).
Phthalimides and N-substituted phthalimides are an important class of compounds because of their interesting biological activities (Lima et al., 2002). In this paper, the structure of the title compound, (I), is reported (Fig. 1). The geometry of molecule is close to the related compounds 2-(2-hydroxyphenyl)isoindoline-1,3-dione (Li et al., 2007) and 2-(4-hydroxyphenyl)isoindoline-1,3-dione (Liang & Li, 2006). The tetrachlorophthalimide moiety system is essentially planar to within 0.019 (3) Å. The nitrophenyl system is planar to within 0.130 (2) Å. The dihedral angle between the nitrophenyl system and the tetrachlorophthalimide moiety is 74.6 (2) °. The crystal packing is shown in Fig. 2.

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. |

Phthalimides and N-substituted phthalimides are an important class of compounds because of their interesting biological activities (Lima et al., 2002). In this paper, the structure of the title compound, (I), is reported (Fig. 1). The geometry of molecule is close to the related compounds 2-(2-hydroxyphenyl)isoindoline-1,3-dione (Li et al., 2007) and 2-(4-hydroxyphenyl)isoindoline-1,3-dione (Liang & Li, 2006). The tetrachlorophthalimide moiety system is essentially planar to within 0.019 (3) Å. The nitrophenyl system is planar to within 0.130 (2) Å. The dihedral angle between the nitrophenyl system and the tetrachlorophthalimide moiety is 74.6 (2) °. The crystal packing is shown in Fig. 2.
