7′-(2,5-Dimethoxyphenyl)-1′,3′,5′,6′, 7′,7a-hexahydrodispiro-[indan-2,5′-pyrrolo-[1,2-c][1,3] thiazole-6′,2″-indan]-1,3,1″-trione

In the title compound, C ₃₀H ₂₅NO ₅S, all the five-membered rings are in envelope conformations with the spiro and methylene C atoms as the flap atoms. Intramolecular C - H⋯O interactions stabilize the molecular structure and form S(6) and S(7) ring motifs. The mean plane through the hexahydropyrrolo-[1,2-c]thiazole ring [r.m.s deviation of 0.0393 (1) Å] makes dihedral angles of 60.92 (5), 88.33 (4) and 84.12 (4)° with the terminal benzene ring and the mean planes of the mono and dioxo substituted indan rings, respectively. molecules are linked by inter-molecular C - H⋯O inter-actions into a three-dimensional network. In addition, C - H⋯π and π-π interactions [centroid-to-centroid distance = 3.4084 (8) Å] further stabilize the crystal structure.
