Abstract top

The absolute structure has been determined by X-ray analysis for the title compound, C11H8Cl2O2. The five-membered ring of the mol­ecule is best described as a flattened envelope conformation with the methyl­ene C atom located 0.208 (2) Å below the plane formed by the other four atoms. A weak intermolecular C-H...O hydrogen bond is present in the crystal structure

Comment top

The title compound was prepared as an intermediate in the search for potential triple neurotransmittor reuptake inhibitors (Milewska et al., 1996; Lin & Charette, 2005; Tsuji et al., 1999; Džolić et al., 2003); details will be published elsewhere.

The molecular structure is shown in Fig. 1. The five-membered ring of the molecule is best described as a flat envelope conformation with C1 located 0.208 (2) Å below the plane constituted by C2, C4, C5 and O1, on the opposite side of C3. In the crystal structure the weak C—H···O hydrogen bonding presents between benzene ring and the carbonyl O atom of the neighboring molecule (Table 1).

Experimental. Crystallized from acetonitrile solution

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. Data were collected by measuring three sets of exposures with the detector set at 2θ = 29°, crystal-to-detector distance 6.00 cm. Refinement of F2 against ALL reflections.
