6-(4-Meth­oxy­phen­yl)naphtho[2,3-b][1]benzothio­phene

The asymmetric unit of the title compound, C(23)H(16)OS, contains two independent mol­ecules with opposite orientations of the meth­oxy groups bonded to the benzene rings. The napthobenzothiophene group in the two molecules is separated by an average distance of 3.912 Å. In both mol­ecules, the napthobenzothio­phene unit is almost planar, with r.m.s deviations of 0.0522 and 0.0143 Å. The meth­oxy­phenyl ring makes dihedral angles of 67.0 (6)° and 70.4 (6)° with respect to the napthobenzothio­phene ring system in the two mol­ecules. The crystal packing features C—H⋯S, π–π [centroid–centroid distances = 3.666 (10) and 3.658 (10) Å] and C–H⋯π inter­actions, forming a sheet running along the b-axis direction.
