3-(4-Bromo-phenyl-sulfin-yl)-5-fluoro-2-methyl-1-benzofuran.

Hong Dae Choi, Pil Ja Seo, Uk Lee.   

Abstract

There are two symmetry-independent mol-ecules, A and B, in the asymmetric unit of the title compound, C(15)H(10)BrFO(2)S. The dihedral angle formed by the 4-bromo-phenyl ring and the mean plane of the benzofuran fragment is 88.26 (6)° in mol-ecule A and 88.25 (6)° in mol-ecule B. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯F, C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits inter-molecular C-Br⋯π [3.737 (3) Å] inter-actions, and weak π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.557 (3) Å, inter-planar distance = 3.421 (3) Å and slippage = 0.974 (3) Å].

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.
