(Received 17 June 2010; accepted 13 August 2010; online 28 August 2010)

In the title compound, C14H4Cl4FNO2, the benzene ring and the phthalimide plane are nearly planar, the maximum deviations being 0.005 (2) and 0.010 (2) Å, respectively, but the mol­ecule as a whole is not planar: the dihedral angle between the two planar ring systems is 68.06 (10)°. A short Cl⋯O contact of 2.914 (2) Å exists in the crystal structure.

Comment top

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. In the title compound, the two rings are nearly planar, the maximum deviations being 0.005 (2) and 0.010 (2) Å, respectively, but the molecule as a whole is not planar. The dihedral angle between the benzene ring and the phthalimide plane is 68.06 (10) °, which is greater than 59.95 (4) ° found in a related compound N-(2-fluorophenyl)phthalimide (Xu et al., 2006). A short Cl···O contact of 2.914 (2) Å exists in the crystal structure.

Experimental top

An acetic acid solution of 4,5,6,7-tetrachlorophthalic anhydride (28.6 g, 100 mmol) and 2-fluoroaniline (9.65 ml, 100 mmol) was refluxed overnight, and then filtered. The crude produce was recrystallized from ethyl acetate.

Refinement top

H atoms were positioned geometrically and refined as riding with C—H = 0.95 Å, and Uiso(H) = 1.2Ueq(C).

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.
