title: Crystal structure of 2,5-dimethyl-3-(2-methyl-phenyl-sulfon-yl)-1-benzo-furan.
abstract: The title compound, C17H16O3S, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the benzo-furan ring system [r.m.s. deviation of 0.013 (1) for A and 0.009 (1) Å for B] and the 2-methyl-phenyl ring is 83.88 (5) for A and 86.94 (5)° for B. In the crystal, the B mol-ecules are linked into a chain along the b-axis direction by C-H⋯O hydrogen bonds. The A mol-ecules are connected on either side of this chain by further C-H⋯O hydrogen bonds. These chains are linked via C-H⋯π inter-actions, forming sheets parallel to (100). There are also very weak π-π inter-actions present [centroid-centroid distance = 3.925 (11) Å] involvingthe 2-methyl-phenyl rings of neighbouring A and B mol-ecules.
