(3aR,8bR)-3a,8b-Dihy-droxy-2-methyl-sulfanyl-3-nitro-1-phenyl-1,8b-di-hydro-indeno[1,2-b]pyrrol-4(3aH)-one.
In the title compound, C18H14N2O5, the pyrrolidine ring adopts a shallow envelope conformation, with the C atom bearing the OH group (and remote from the N atom) displaced by 0.257 (2) Å from the other atoms. The cyclo-pentane ring has a twisted conformation about the C-C bond bearing one =O and one -OH grouping. The dihedral angle between the five-membered rings (all atoms) is 65.54 (9)° and the OH groups lie to the same side of the ring-junction. The mol-ecular structure features a weak intra-molecular O-H⋯O bond and a possible C-H⋯π inter-action. In the crystal, the mol-ecules are linked into [010] chains by O-H⋯O hydrogen bonds. Weak C-H⋯O bonds connect the chains into (100) sheets.
