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

Abstract

In the title compound, C30H25NO5S, 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.
