YL)-1-(PHENYL-SULFONYL)VINYL]-3-(PHENYLTHIO)INDOLE

The dioxole ring of the title compound, C29H21NO4S2, is inclined at an angle of 67.9 (2)degrees to the indole ring system. The phenyl rings of the phenylsulfonyl and phenylthio substituents are almost perpendic ular to each other [73.3 (2)degrees], while the phenylthio and the phe nyl ring of the methylenedioxyphenyl ring system are almost parallel t o each other [8.2 (2)degrees]. The indole ring system is slightly fold ed along the central C-C bond (2.10). All the rings are quite planar. The molecules are linked by N-H...O-type hydrogen bonds.
