چکیده
In the title compound, C(28)H(20)BrNO(3)S, the thia-zolidine, 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 mol-ecular structure features an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked into inversion dimers by pairs of C-H⋯O hydrogen bonds.
