In the title compound, C14H8ClNO3, the central ester CO2 group is twisted away from the quinoline and furoyl rings by 57.46 (5) and 2.0 (1)°, respectively. In the crystal, molecules are linked by weak C—H⋯O interactions, forming chains in [001].

The reagents and solvents for the synthesis were obtained from the Aldrich Chemical Co. and were used without additional purification. In a 100 ml round bottom flask 2-furoyl chloride (1.564 mmol, 0.204 g) and 5-chloro-8hidroxyquinoline (1.564 mmol, 0.260 g) in equimolar amounts were mixed. The mixture was left to reflux in 20 ml of acetonitrile in constant stirring for about two hours, adding small amounts of pyridine as catalyst. A colourless solid was obtained after leaving the solvent to evaporate. IR spectra were recorded on a FT—IR SHIMADZU IR-Affinity-1 spectrophotometer. Colourless crystals; m.p 389 (1) K. IR (KBr) 3127 cm-1, 3097 cm-1 (aromatic C—H); 1743 cm-1 (ester C=O), 1299 cm-1 (ester C-O); 1588 cm-1, 1495 cm-1, 1392 cm-1 (amine C—N); 1467 cm-1 (furan C-O); 1181 cm-1 (C=C); 936 cm-1 (Cl-C).
All the H-atoms attached to C atoms were positioned at geometrically idealized positions and treated as riding with C—H= 0.93 Å and Uiso(H) = 1.2 Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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, C14H8ClNO3 [5-chloroquinolin-8-yl-furan-2-carboxylate] (I), is part of a series of studies on the structural properties of the quinoline fragment developed by our research group. The quinoline ring exhibits a key factor responsible for a wide range of medicinal (Somvanshi et al., 2008), antifungal (Biavatti et al., 2002) and antibacterial (Towers et al., 1981) properties. The quinoline ring has been also used in anticancer studies (Shen et al., 1999), as well as its derivatives have been exploited for their luminescent properties as organic light-emitting diodes (OLED) materials (Montes et al., 2006). The molecular structure of (I) is shown in Fig. 1. Bond lengths and bond angles of (I) show marked similarity with other 8-Hydroxyquinoline benzoates reported in the literature such as 8-Quinolyl benzoate and 2-Methylquinolin-8-yl 2-nitrobenzoate (Lei, 2006 and 2007). The central ester moiety, C8/O1/C10/O2/C11, is essentially planar with a r.m.s deviation of fitted atoms of 0.007 Å. The ester group is twisted away from the quinoline and furoyl rings by 57.45 (5)° and 2.0 (1)°, respectively. The crystal packing shows no classical hydrogen bonds. The crystal packing is stabilized by weak C-H···O intermolecular interactions, forming C(6) chains along [001] (see Fig. 2; Etter, 1990). The C14 atom of the furoyl ring at (x,y,z) acts as a hydrogen-bond donor to carbonyl atom O2 at (x-1,-y+1/2,+z-1/2) (see Table 1; Nardelli, 1995).
