چکیده
In the title compound, C20H15BrO2S, the dihedral angle between the mean plane [r.m.s. deviation = 0.030 (2) Å] of the naphtho-furan ring system and the 4-methyl-phenyl ring is 38.49 (9)°. In the crystal, mol-ecules are linked by C-H⋯π and C-Br⋯π [3.871 (2) Å] inter-actions into stacks along the b-axis direction. These stacks are further linked by weak C-H⋯O hydrogen bonds, forming a three-dimensional network.
