Tht title compound was synthesized from a mixture of isoindoline-1,3-dione (5 mmol, 0.736 g) and 3-chloropropanenitrile (5 mmol, 0.448 g) and triethylamine (8 mmol, 0.505 g) and 30 ml N,N-dimethylformamide. The components were dissolved in 20 ml e thanol and 2 ml water, then heated to boiling and stirred for ten minutes. The system was cooled to the room temperature and colourless blocks of (I) were collected after six days.
Isoindoline-1,3-dione derivatives exhibit a high level of biological activity (Wingrove & Caret, 1981). As a part of our studies in this area, we have isolated the title compound, (I), (Fig. 1).
As expected, the six-membered and five-membered rings are almost co-planar [dihedral angle = 0.67 (6)°]. In the crystal of (I), C—H···O and C—H···N interactions (Table 1) help to establish the packing (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. |
