A solution of phthaloyl dichoride (420, 2 mmol) was added slowly over a period of 10 min to a solution of 4-(4-aminobenzyl)benzenamine (240 mg, 2 mmol) in dichloromethane (20 ml) at 273 K with light yellow solid precipitated. Triethylamine (5 ml) was then added, while the pecipitated light yellow solid was dissolved. After being stirred for 10 hr,the reacted solution became yellow suspension.The compound was purified by filtration with suction and dried (I) (yield 410 mg, 29.14%). Single crystals of (I) were obtained by recrystallization from DMF at room temperature.
All H atoms were initially located in a difference Fourier map and then included with constrained bond lengths and isotropic displacement parameters: C—H=0.93Å and Uiso(H)=1.5Ueq(C) for methyl, C—H=0.97Å and Uiso(H)=1.2Ueq(C) for methylene.
Bisimides are heterocyclic compounds, of which some have biological activivity. Moreover, they are synthetic precursor with application in organic synthesis, supramolecular chemistry, polymer synthesis, and for the development new materials and molecular electronic devices (Guzmán-Lucero et al., 2006).
The molecule of the title, (I) is shown in Fig. 1. The compound crystallizes with one half-molecule in the asymmetric unit, the other half being generated by a crystallographic twofold rotation axis passing through the central C atom. There are no signicant different between the bonds and angles of the two molecules. The dihedral angle between the planes of the two central benzene rings is 67.7 (4)°. The terminal isoindole group is approximately planar and makes adihedral angle of 39.20 (17)° with the attached benzene ring.
Intermolecular C—H···O hydrogen bonds contribute to the stability of the structure (Table 1).

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. |

Bisimides are heterocyclic compounds, of which some have biological activivity. Moreover, they are synthetic precursor with application in organic synthesis, supramolecular chemistry, polymer synthesis, and for the development new materials and molecular electronic devices (Guzmán-Lucero et al., 2006).
The molecule of the title, (I) is shown in Fig. 1. The compound crystallizes with one half-molecule in the asymmetric unit, the other half being generated by a crystallographic twofold rotation axis passing through the central C atom. There are no signicant different between the bonds and angles of the two molecules. The dihedral angle between the planes of the two central benzene rings is 67.7 (4)°. The terminal isoindole group is approximately planar and makes adihedral angle of 39.20 (17)° with the attached benzene ring.
Intermolecular C—H···O hydrogen bonds contribute to the stability of the structure (Table 1).
