In the title molecule, C10H7ClO3, the butyrolactone core, a furan-2(5H)-one, forms a dihedral angle of 59.21 (5)° with the benzene ring. In the crystal, two types of hydrogen bonds (O—H⋯O and C—H⋯Cl) link molecules into infinite chains along the b axis. π–π contacts [centroid–centroid distances = 3.6359 (10) and 3.8776 (11) Å] link the chains into a three-dimensional network.

A dropwise solution of 2-ethoxy-2-oxoethyl 2-(2-chlorophenyl)acetate (1.03 g, 4 mmol) in dry THF was added to a suspension of NaH in dry THF in an ice cold bath. The stirring was maintained at room temperature for 6 h. Water was added and the solution was extracted twice with ethyl ether. The aqueous phase was cooled to 273 K and then acidified with concentrated hydrochloric acid to give a solid precipitate. The title compound thus obtained was crystallized from ethanol-water (2:1) to give the colorless blocks suitable for single-crystal structure determination.
The H-atoms bonded to C-atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with C—H = 0.93 and 0.97 Å for aryl and methylene type H atoms, respectively, with Uiso(H) = 1.2 Ueq(C). The hydroxyl H atom was located from a difference Fourier map and was allowed to refine freely.
Recently, we have reported the antibacterial activities of a few γ-butyrolactones (furanones) (Xiao et al., 2011). As a part of our ongoing studies of γ-butyrolactones (Xiao et al., 2010), we herein report the of the title compound.
In the title compound (Fig. 1), the butyrolactone moiety makes a dihedral angle of 59.21 (5) ° with the benzene ring. Relatively strong intermolecular hydrogen bonds (O—H···O) link molecules into an infinite chain running along the b axis, which is further consolidated by weak intermolecular C—H···Cl interactions. There are π–π contacts between benzene rings and butyrolactone rings with centroid–centroid distances 3.6359 (10) and 3.8776 (11) Å, respectively (Fig. 2). The molecular dimensions in the title molecule agree very well with the corresponding molecular dimensions reported in a few similar structures (Peng et al., 2011; Xiao et al., 2010).

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. |

Recently, we have reported the antibacterial activities of a few γ-butyrolactones (furanones) (Xiao et al., 2011). As a part of our ongoing studies of γ-butyrolactones (Xiao et al., 2010), we herein report the crystal structure of the title compound.
In the title compound (Fig. 1), the butyrolactone moiety makes a dihedral angle of 59.21 (5) ° with the benzene ring. Relatively strong intermolecular hydrogen bonds (O—H···O) link molecules into an infinite chain running along the b axis, which is further consolidated by weak intermolecular C—H···Cl interactions. There are π–π contacts between benzene rings and butyrolactone rings with centroid–centroid distances 3.6359 (10) and 3.8776 (11) Å, respectively (Fig. 2). The molecular dimensions in the title molecule agree very well with the corresponding molecular dimensions reported in a few similar structures (Peng et al., 2011; Xiao et al., 2010).
