N-(p-Nitrophenylsulfonyl)-1H-pyrrole

Abstract

In the title compound, C10H8N2O4S, the dihedral angle between the pyrrole and benzene rings is 77.9 (1)°. Intermolecular C—H⋯O hydrogen bonds stabilize the crystal structure, forming molecular chains extending approximately parallel to the c axis and stacked along the b axis.

“…It is well known that nitro substituents are very strong electron-withdrawing groups, so the C1-C2- C3 [113.3 (2) ] angle is enlarged. On the other hand, the electron-withdrawing character of the nitro group has an influence on the C2-N1 [1.496 (3) Å ] bond length, as in N-(p-nitrophenylsulfonyl)-1H-pyrrole (Gü ltekin et al, 2004).…”
