In the title compound, C14H8FNO2, the dihedral angle
between the two planar ring systems is 59.95 (4).
Comment
The crystal structure of the title compound, (I), has been determined in order to elucidate the molecular conformation. The dihedral angle between the benzene ring and the phthalimide plane is 59.95 (4).
Experimental
Compound (I) was prepared from phthalic anhydride and 2-fluoro-aniline (Barchin et al., 2002). An acetic acid solution of phthalic anhydride (14.8 g, 100 mmol) and 2-fluoroaniline (11.1 g, 100 mmol) was refluxed overnight, and then filtered. The crude product was washed with water three times, and dried. The compound (I) was recrystallized from ethyl acetate (m.p. 465 K).

The F atom is disordered over two ortho positions with refined occupancies of 0.681 (3) and 0.319 (3). All H atoms were initially located in a difference Fourier map. All H atoms were then constrained to an ideal geometry, with C—H distances of 0.93 A˚ and
Uiso(H) = 1.2Ueq(C).

Special details
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 > 2σ(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.
