N-[(2S)-2-(4-Bromo-phen-yl)-4-oxo-1,3-thia-zolidin-3-yl]pyridine-3-carboxamide

5-Chloro-N-{4-oxo-2-[4-(trifluoro-meth-yl)phen-yl]-1,3-thia-zolidin-3-yl}-3-phenyl-1H-indole-2-carboxamide

In the title compound, C(25)H(17)ClF(3)N(3)O(2)S, the five-membered 1,3-thia-zolidine ring adopts a twist conformation. The three F atoms of the CF(3) group are disordered over two sets of sites with refined occupancies of 0.542 (18) and 0.458 (18). In the nine-membered 1H-indoline ring system, the 1H-pyrrole ring forms a dihedral angle of 4.7 (2)° with the benzene ring, while it is twisted at an angle of 46.5 (2)° with respect to the attached phenyl ring. The dihedral angle between the phenyl and trifluoro-methyl-substituted benzene rings is 56.0 (2)°. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into a three-dimensional network. In addition, weak C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions are observed.

2-(4-Bromo-phen-yl)-3-(4-hy-droxy-phen-yl)-1,3-thia-zolidin-4-one

In the title compound, C₁₅H₁₂BrNO₂S, the dihedral angle between the two aromatic rings is 87.81 (8)°. The five-membered thia­zolidine ring has an envelope conformation, with the S atom displaced by 0.4545 (7) Å from the mean plane of the other four ring atoms. The crystal structure exhibits O—H⋯O, C—H⋯O, C—H⋯Br and C—H⋯ π inter­actions.
