Crystal structure of 5-chloro-2-(3-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzo-furan

Crystal structure of 5-chloro-2-(2-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzo-furan

In the title compound, C15H10ClFO2S, the dihedral angle between the mean planes of the benzo-furan ring [r.m.s. deviation = 0.007 (1) Å] and the 2-fluoro-phenyl ring is 32.53 (5)°. In the crystal, mol-ecules related by inversion are paired into dimers via two different C-H⋯O hydrogen bonds. Further, Cl⋯O halogen bonds [3.114 (1) Å], and F⋯π [F-to-furan-centroid distance = 3.109 (1) Å] and S⋯F [3.1984 (9) Å] inter-actions link these into a three-dimensional network.

In the title compound, C₁₅H₁₀FIO₂S, the dihedral angle between the planes of the benzo­furan ring system [r.m.s. deviation = 0.015 (2) Å] and the 3-fluoro­phenyl ring is 29.63 (7)°. In the crystal, mol­ecules are linked into inversion dimers along the b-axis direction by two different pairs of C—H⋯O hydrogen bonds and I⋯O [3.228 (1) Å] contacts.

In the title compound, C₁₅H₁₀F₂O₂S, the dihedral angle between the planes of the benzo­furan ring system [r.m.s. deviation = 0.015 (1) Å] and the 3-fluoro­phenyl ring is 26.60 (5)°. In the crystal, mol­ecules are linked by C—H⋯O and C—H⋯F hydrogen bonds, and by π–π inter­actions between the benzo­furan rings of inversion-related mol­ecules [centroid(benzene)–centroid(furan) distance = 3.819 (2) Å], forming a three-dimensional network.
