2-Bromo-1,2-diphenylethenyl 4-methyl-phenyl sulfoxide.

In the title compound, C(21)H(17)BrO(2)S, the two phenyl rings attached to the ethene group are oriented at dihedral angles of 76.19 (10) and 57.99 (8)° with respect to the Br-C=C-S plane [r.m.s. deviation 0.003 Å]. The sulfonyl-bound phenyl ring forms a dihedral angle of 83.26 (8)° with the above plane. The crystal structure is stabilized by weak C-H⋯π inter-actions.
