1-(4-Bromo-phenyl-sulfin-yl)-2-methyl-naphtho-[2,1-b]furan
Abstract:
In the title compound, C(19)H(13)BrO(2)S, the 4-bromo-phenyl ring makes a dihedral angle of 83.75 (4)° with the mean plane of the naphtho-furan fragment [r.m.s. deviation = 0.024 (2) Å]. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by weak π-π inter-actions between the central naphtho-furan benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.483 (2) Å, inter-planar distance = 3.416 (2) Å and slippage = 0.680 (2) Å].
