چکیده
The title compound, C(24)H(15)BrO(2)S·0.5C(6)H(6), crystallizes as a benzene hemisolvate. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the naphthofuran fragment, and the phenyl ring is almost perpendicular to the plane of the naphthofuran fragment [83.78 (8)°] and is tilted slightly towards it. The 2-phenyl ring is rotated out of the naphthofuran plane by a dihedral angle of 25.2 (1)°. The crystal structure is stabilized by aromatic π-π inter-actions between the central benzene ring and the furan ring of the neighbouring naphthofuran systems [centroid-centroid distance = 3.611 (3) Å], and by inter-molecular C-H⋯π inter-actions between the benzene H atom of the phenyl-sulfinyl substituent and the 2-phenyl ring of an adjacent mol-ecule. In addition, the crystal structure exhibits a weak non-classical inter-molecular C-H⋯O hydrogen bond.
