(3aR,8bR)-3a,8b-Dihy­droxy-2-methyl­sulfanyl-3-nitro-1-phenyl-1,8b-di­hydro­indeno[1,2-b]pyrrol-4(3aH)-one

In the title compound, C(18)H(14)N(2)O(5), 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 cyclo­pentane 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 mol­ecular structure features a weak intra­molecular O—H⋯O bond and a possible C—H⋯π inter­action. In the crystal, the mol­ecules are linked into [010] chains by O—H⋯O hydrogen bonds. Weak C—H⋯O bonds connect the chains into (100) sheets.
