In the title compound, C15H10FNO3, the dihedral angle between the isoindoline-1,3-dione and 3-fluoro-4-methylphenol groups is 86.88 (8)°. The isoindoline-1,3-dione fragment is almost planar, with an r.m.s. deviation of 0.0154 Å within the group. Intermolecular C—H⋯O hydrogen bonds generate C(6) chains running parallel to the [010] direction.

The compound 2-(2-fluoro-4-hydroxybenzyl)-1H-isoindole-1,3(2H)-dione was prepared by combining solutions of 2-hydroxy-1H-isoindole-1,3(2H)-dione (0.011 g 0.067 mmol) in 20 ml of ethanol and 1-(2,4-difluorophenyl)methanamine (0.009 g, 0.067 mmol) in 20 ml of ethanol and refluxing the resulting mixture for 1 h with stirring. Crystals of 2-(2-fluoro-4-hydroxybenzyl)-1H-isoindole-1,3(2H)-dione suitable for X-ray analysis were obtained from ethyl alcohol by slow evaporation (yield 72%; m.p. 155–158°C).
The H1 atom was located in a difference map and the O—H distance adjusted to 0.82 (2) Å while the other H atoms were placed in calculated positions. All were constrained to ride on their parent atoms, with C—H = 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C,O).
Indoline-2,3-dione and its derivatives are well known for their broad spectrum properties including anticonvulsant (Bhattacharya & Chakrabarti, 1998), anti-inflammatory (Sridhar & Ramesh, 2001) and anxiogenic (Medvedev et al., 1996) activities. On the other hand, dithiocarbamates also show a large range of biological activities for example fungicidal (Ozkirimli et al., 2005) and antitumor activities (Cao et al., 2005; Gaspari et al., 2006).
As an extension of the work on the structural characterization of indoline-2,3-dione derivatives, the
of the title compound is reported here. The isoindoline-1,3-dione fragment is almost planar with an r.m.s. deviation of 0.0154 Å within the group. This unit makes a dihedral angle of 86.88 (8)° with the benzene ring.The F1—C4 bond length of 1.349 (3) Å agrees with the corresponding distance in 9-(7-fluoro-4-oxo-4H-chromen-3-yl)-3,3,6,6-tetramethyl-2,3,4,5,6, 7,8,9-octahydro-1H-xanthene-1,8-dione [1.349 (2) Å (Asad et al., 2012)]. The C═O bond lengths are 1.205 (3) Å for C8═O2 and C11═O3 which are similar to the corresponding values found in 2-(2-oxothiolan-3-yl)isoindoline-1,3-dione [1.202 (5) Å and 1.207 (5) Å (Raza et al., 2010)].
The molecules are linked into sheets by a combination of C—H···O and O—H···F interactions (Table 1). C(6) chains along [010] are created by pairwise C12—H12···O2 and C15—H15···O3 hydrogen bond interactions. The combination of the C(6) chains generates chain edge-fused R22(10) rings running along [010]. C(6) chains along [001] are formed by O1—H1···F1 hydrogen bond interactions (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. |

Indoline-2,3-dione and its derivatives are well known for their broad spectrum properties including anticonvulsant (Bhattacharya & Chakrabarti, 1998), anti-inflammatory (Sridhar & Ramesh, 2001) and anxiogenic (Medvedev et al., 1996) activities. On the other hand, dithiocarbamates also show a large range of biological activities for example fungicidal (Ozkirimli et al., 2005) and antitumor activities (Cao et al., 2005; Gaspari et al., 2006).
As an extension of the work on the structural characterization of indoline-2,3-dione derivatives, the crystal structure of the title compound is reported here. The isoindoline-1,3-dione fragment is almost planar with an r.m.s. deviation of 0.0154 Å within the group. This unit makes a dihedral angle of 86.88 (8)° with the benzene ring.
The F1—C4 bond length of 1.349 (3) Å agrees with the corresponding distance in 9-(7-fluoro-4-oxo-4H-chromen-3-yl)-3,3,6,6-tetramethyl-2,3,4,5,6, 7,8,9-octahydro-1H-xanthene-1,8-dione [1.349 (2) Å (Asad et al., 2012)]. The C═O bond lengths are 1.205 (3) Å for C8═O2 and C11═O3 which are similar to the corresponding values found in 2-(2-oxothiolan-3-yl)isoindoline-1,3-dione [1.202 (5) Å and 1.207 (5) Å (Raza et al., 2010)].
The molecules are linked into sheets by a combination of C—H···O and O—H···F interactions (Table 1). C(6) chains along [010] are created by pairwise C12—H12···O2 and C15—H15···O3 hydrogen bond interactions. The combination of the C(6) chains generates chain edge-fused R22(10) rings running along [010]. C(6) chains along [001] are formed by O1—H1···F1 hydrogen bond interactions (Fig.2).
