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

Abstract: In the title compound, C19H16N2O6S, the pyrrolidine ring adopts a twisted conformation with puckering parameters q2 = 0.088 (3) Å and [Phi]2 = 61.5 (14)°. The cyclo­pentane ring adopts a twisted conformation with puckering parameters q2 = 0.099 (2) Å and [Phi]2 = 242.8 (14)°. A weak intra­molecular O-H...O inter­action occurs. In the crystal, pairs of C-H...O inter­actions generate dimers with graph-set motif R22(24) and they are interconnected by pairs of O-H...O hydrogen bonds, which link the mol­ecules into inversion dimers with graph-set motif R22(10).
