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(30)H(25)NO(5)S, 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 di-oxo substituted indan rings, respectively. Mol­ecules are linked by inter­molecular C—H⋯O inter­actions 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.
