Abstract

The ?-lactam (azetidin-2-one) ring of the title compound, C 28H27N3O5, is nearly planar [maximum deviation = 0.010 (1) Å] and makes dihedral angles of 75.77 (5), 52.78 (9) and 88.72 (5)°, respectively, with the benzene ring, the least-squares plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, and the xanthene ring system. In the crystal, C - H?O hydrogen-bond contacts connect neighbouring molecules into infinite zigzag chains running parallel to the b axis., Akkurt, M.; Department of Physics, Faculty of Sciences, Erciyes University, 38039 Kayseri, Turkey; email: akkurt@erciyes.edu.tr

Abstract

In the title compound, C25H17C1F3N 3O2S, the five-membered 1,3-thiazolidine ring adopts a twist conformation. The three F atoms of the CF3 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 trifluoromethyl-substituted benzene rings is 56.0 (2)°. In the crystal, N - H···O hydrogen bonds connect the molecules into a three-dimensional network. In addition, weak C - H···O hydrogen bonds and weak C - H··· ? interactions are observed., Akkurt, M.; Department of Physics, Faculty of Sciences, Erciyes University, 38039 Kayseri, Turkey; email: akkurt@erciyes.edu.tr

However, the relatively wide range of Br - C - C angles [ 107.2 ( 5) - 117.0 ( 4)degrees] in the five- membered ring may indicate repulsion between the neighbouring Br atoms. The crystal packing is stabilized by van der Waals interactions.
