چکیده
The title mol-ecule, C(18)H(17)NO(4)S, features a 1,3-thia-zolidine ring that is twisted about the S-C(methyl-ene) bond. With reference to this ring, the 1,3-benzodioxole and benzene rings lie to either side and form dihedral angles of 69.72 (16) and 83.60 (14)°, respectively, with the central ring. Significant twisting in the mol-ecule is confirmed by the dihedral angle of 79.91 (13)° formed between the outer rings. Linear supra-molecular chains along the a-axis direction mediated by C-H⋯O inter-actions feature in the crystal packing.

In the title compound, C(17)H(12)O(3), each of the five-membered rings in the inden-1-one and 1,3-benzodioxole residues is almost planar (r.m.s. deviations = 0.041 and 0.033 Å, respectively). A small twist about the single bond linking the two residues is evident [the C-C-C-C torsion angle = 8.7 (4)°]. Supra-molecular zigzag layers propagating in the ac plane are formed in the crystal via C-H⋯O...
