The title compound was prepared by a method reported in the literature, see: Zeng et al. (2006). The crystals were obtained by dissolving the compound (0.1 g) in dichloromethane (5 ml) and then evaporating the solvent slowly at room temperature for about 3 days.
All H atoms were refined as riding atoms with isotropic displacement parameters 1.2 times larger or 1.5 times larger (methyl H) than the corresponding host carbon atoms. The methyl H atoms' positions were set based using AFIX 33 instruction in SHELXL97 (Sheldrick, 2008)). The C—H distances were kept at 0.95 Å (0.98 Å for methyl hydrogens).
The (E)-2-[2-(3-fluorophenyl)ethenyl]-8-acetoxyquinoline was prepared via a reaction of 2-methyl-8-hydroxyquinaldine with 3-fluorobenzaldehyde according to Zeng et al. (2006). The molecular structure is shown on Fig. 1. There are non- classical intermolecular hydrogen bonds C–H···O between carbonyl oxygen and the methyl group (C···O = 3.495 (2) Å; C–H···O = 166°) connecting molecules into chains along the b axis.
For the synthetic procedure, see: Zeng et al. (2006).

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 (E)-2-[2-(3-fluorophenyl)ethenyl]-8-acetoxyquinoline was prepared via a reaction of 2-methyl-8-hydroxyquinaldine with 3-fluorobenzaldehyde according to Zeng et al. (2006). The molecular structure is shown on Fig. 1. There are non- classical intermolecular hydrogen bonds C–H···O between carbonyl oxygen and the methyl group (C···O = 3.495 (2) Å; C–H···O = 166°) connecting molecules into chains along the b axis.
