3-Ethyl-sulfinyl-2-(4-fluoro-phen-yl)-5-iodo-1-benzofuran.

ABSTRACT: In the title compound, C(16)H(12)FIO(2)S, the 4-fluoro-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 4.48?(5)°. In the crystal structure, pairs of I?O halogen bonds [I?O = 3.123?(1)?Å] link the mol-ecules into centrosymmetric dimers. These dimers are further linked via aromatic ?-? inter-actions between the benzene and 4-fluoro-phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.620?(3)?Å].

In the title compound, C(16)H(12)FIO(2)S, the 4-fluoro-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 4.48 (5)°. In the crystal structure, pairs of I⋯O halogen bonds [I⋯O = 3.123 (1) Å] link the mol-ecules into centrosymmetric dimers. These dimers are further linked via aromatic π-π inter-actions between the benzene and 4-fluoro-phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.620 (3) Å]. ...[more]
