Propyl 2-(5-bromo-3-methyl-sulfinyl-1-benzofuran-2-yl)acetate.

In the title compound, C(14)H(15)BrO(4)S, the S atom has a distorted trigonal-pyramidal coordination. The O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The mol-ecules form slightly slipped π-stacked inversion-symmetric dimers by inter-molecular aromatic π-π inter-actions, with a centroid-to-centroid distance of 3.695 (4) Å between the benzene rings of neighbouring mol-ecules. The crystal packing is further stabilized by inter-molecular C-H⋯π inter-actions between the methyl-ene H atoms of the propyl group towards the benzene and furan rings of neighbouring mol-ecules, respectively. Additionally, the crystal structure exhibits weak inter-molecular C-H⋯O hydrogen bonds.

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 > 2sigma(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.
