3,4-Dibromo-2,5-bis[(diethoxyphosphoryl)methyl]-1-phenylsulfonyl-1H-pyrrole
In the title compound, C20H29Br2NO8P2S, the pyrrole ring is essentially planar, with a maximum deviation of 0.013 (3) Å for a C atom. The pyrrole ring is almost orthogonal to the sulfonyl-bound phenyl ring, with a dihedral angle 88.5 (2)°. Both P atoms exhibit distorted tetrahedral configurations with O—P—O angles widened and O—P—C angles narrowed from the ideal tetrahedral value. In the crystal, molecules are linked into centrosymmetric dimers via C—H⋯O interactions, resulting in R

2(13) graph-set ring motifs via C—H⋯O interactions, further resulting in chains of molecules running parallel to the c axis; a phosphono O atom is involved in bifurcated hydrogen bonding. All the ethoxy groups are disordered over two positions each with unequal site-occupancy factors
2-Azidomethyl-3-methyl-1-phenylsulfonyl-1H-indole
In the title compound, C16H14N4O2S, the plane of the indole ring is twisted by 70.4 (2)° with respect to the plane of the azidomethyl substituent. As a result of the electron-withdrawing character of the phenylsulfonyl groups, the N—C bond lengths are slightly longer than the anticipated value of approximately 1.355 Å for an N atom with a planar configuration. The indole ring is essentially planar, with a maximum deviation of 0.0296 Å. The azide group is almost linear, the N—N—N angle being 171.4 (3)°. The methyl group on the azide-substituted C atom is in a flagpole position. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 87.07 (10)° with the best plane of the indole moiety. The crystal packing is stabilized by intermolecular C—H⋯O interactions, which link the molecules into infinite chains running parallel to the b axis. The crystal packing is further stabilized by C—H⋯π interactions
Diethyl [(3-cyano-1-phenylsulfonyl-1H-indol-2-yl)methyl]phosphonate
In the title compound, C20H21N2O5PS, the indole ring is essentially planar, with a maximum deviation of −0.0083 (18) Å. The methyl C atom of the methylphosphonate group and the S atom lie 0.104 (2) and −0.2158 (6) Å, respectively, from the indole mean plane. The sulfonyl-bound phenyl ring is almost perpendicular to the indole ring system, with a dihedral angle of 82.30 (8)°. The ethyl side chains are disordered over two sets of sites, with occupancy factors of 0.737 (5)/0.263 (5) and 0.529 (11)/0.471 (11). In the crystal, molecules are linked into centrosymmetric dimers via C—H⋯O hydrogen bonds, resulting in an R

(E)-3-(2-Nitrophenyl)-1-{1-phenylsulfonyl-2-[(phenylsulfonyl)methyl]-1H-indol-3-yl}prop-2-en-1-one
In the title compound, C30H22N2O7S2, the configuration about the propene C=C bond is E. The indole unit is essentially planar, with a maximum deviation of 0.031 (3) Å. The dihedral angle between the planes of the phenyl rings of the two phenylsulfonyl groups is 80.95 (19)°. The central prop-2-ene-1-one group is oriented at a dihedral angle of 44.26 (11)° with respect to the nitrophenyl ring and at 39.24 (8)° with respect to the indole unit. The S atoms are in a distorted tetrahedral configuration. In the crystal, molecules are linked into centrosymmetric dimers via pairs of C—H...O hydrogen bonds with an R22(24) graph-set motif. The crystal structure is stabilized by further C—H...O interactions. Short intramolecular C—H...O contacts result in several S(6) rings
