6-(4-Meth-oxy-phen-yl)naphtho[2,3-b][1]benzothio-phene.

ABSTRACT: The asymmetric unit of the title compound, C23H16OS, contains two independent mol-ecules with opposite orientations of the meth-oxy 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 mol-ecules, the napthobenzothio-phene unit is almost planar, with r.m.s deviations of 0.0522 and 0.0143 Å. The meth-oxy-phenyl ring makes dihedral angles of 67.0 (6)° and 70.4 (6)° with respect to the napthobenzothio-phene ring system in the two mol-ecules. The crystal packing features C-H⋯S, π-π [centroid-centroid distances = 3.666 (10) and 3.658 (10) Å] and C-H⋯π inter-actions, forming a sheet running along the b-axis direction.
