In the title compound, C10H2Cl4F3NO2, the isoindoline ring system is almostplanar, the maximum atomic deviation being 0.064 (2) Å. The C—C bond of the ethylene group is twisted with respect to the isoindoline plane by a dihedral angle of 59.58 (12)°. In the crystal, weak intermolecular C—H⋯F hydrogen bonding links the molecules into supramolecular chains running along the a axis. A short intermolecular Cl⋯O contact of 2.950 (3) Å is also observed.

An acetic acid solution of tetrachlorophthalic anhydride (28.6 g, 100 mmol) and 2,2,2-trifluoroethylamine (7.99 ml, 100 mmol) was refluxed overnight, and then filtered. The crude produce was recrystallized from ethyl acetate.
H atoms were positioned geometrically and refined as riding with C—H = 0.99 Å, and Uiso(H) = 1.2Ueq(C).

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. |

The title compound is a key intermediate in the synthesis of organic electro-luminescent materials. The emission of light by organic molecules exposed to an electric field has been wide investigated in both an academic and industrial context (Han & Kay, 2005).
The molecular structure of the title compound is illustrated in Fig. 1. The isoindole ring system is planar, the maximum atomic deviation being 0.064 (2)Å (for C8 atom). The C9—C10 bond of the ethylene group is twisted with respect to the isoindole ring by a dihedral angle of 59.58 (12)°, which is similar to 60.3 (5)° found in a related compound 2-(2-iodoethyl)isoindole-1,3-dione (Valkonen et al. 2007). Weak intermolecular C—H···F hydrogen bonding is present in the crystal structure (Table 1).
