7′-(4-Bromophenyl)-5′,6′,7′,7a'-tetrahydrodispiro[indan-2,5′-pyrrolo[1,2-c][1,3]thiazole-6′,2′′-indan]-1,3,1′′-trione

Abstract

In the title compound, C28H20BrNO3S, the thiazolidine, pyrrolidine and two five-membered carbocyclic rings are in envelope conformations. The bromo-bound phenyl ring forms dihedral angles of 61.97 (18) and 88.30 (17)° with the other two benzene rings. The two benzene rings form a dihedral angle of 30.3 (2)°. The molecular structure features an intramolecular C—H...O hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked into inversion dimers by pairs of C—H...O hydrogen bonds.
