(3aR*,8bR*)-3a,8b-Dihy-droxy-1-(4-methyl-phen-yl)-2-methyl-sulfanyl-3-nitro-1,8b-di-hydro-indeno-[1,2-b]pyrrol-4(3aH)-one.

ABSTRACT: The asymmetric unit of the title compound, C19H16N2O5S, contains four independent mol-ecules (A, B, C and D), with two mol-ecules (B and D) displaying disorder in their methyl-sulfanyl groups [occupancy ratios of 0.797 (11):0.203 (11) and 0.85 (2):0.15 (2)]. The nitro groups are twisted slightly out of the planes of the 2-pyrroline rings to which they are bonded with dihedral angles of 10.17 (1), 8.01 (1), 9.44 (1) and 8.87 (1)° in mol-ecules A, B, C and D, respectively. The 2-pyrroline rings are almost orthogonal to the attached tolyl rings, forming dihedral angles of 73.44 (1), 81.21 (1), 88.18 (8) and 73.94 (1)° for mol-ecules A, B, C and D, respectively. A weak intra-molecular O-H⋯O inter-action is observed in mol-ecules B and C. The two hy-droxy groups in each mol-ecule are involved i
