2-(4-Bromophenyl)-2-oxoethyl anthracene-9-carboxylate
(2012) Fun, H.-K.; Asik, S.I.J.; Garudachari, B.; Isloor, A.M.; Satyanarayan, M.N.
In the title compound, C23H15BrO3, the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) ] and makes a dihedral angle of 5.74 (8) with the mean plane of the bromo-substituted benzene ring. An intramolecular C - H?O hydrogen bond generates an S(9) ring motif. In the crystal, molecules are linked by C - H?O interactions, forming a two-dimensional network parallel to the ac plane. ?-? stacking interactions are observed between benzene rings [centroid-centroid distances = 3.5949 (14) and 3.5960 (13) ].

2-(4-Chloro-phen-yl)-2-oxoethyl 2-meth-oxy-benzoate
(2011) Fun, H.-K.; Asik, S.I.J.; Garudachari, B.; Isloor, A.M.; Satyanarayan, M.N.
In the title compound, C 16H 13ClO 4, the two benzene rings make a dihedral angle of 86.38 (8) . In the crystal, inter-molecular C - H?O hydrogen bonds link the mol-ecules to form columns along the a axis. The mol-ecules are also stabilized by a ?-? stacking inter-action, with a centroid-centroid distance of 3.7793 (10) between the inversion-related benzene rings. Fun et al. 2011.

4-(3-Chlorophenyl)-3-[(2,6-difluorobenzyl)sulfanyl]-5-(3,4, 5-trimethoxyphenyl)-4H-1,2,4-triazole
(2011) Fun, H.-K.; Asik, S.I.J.; Chandrakantha, B.; Isloor, A.M.; Shetty, P.
In the title compound, C24H20ClF2N 3O3S, the essentially planar triazole ring (r.m.s. deviation = 0.001 ) forms dihedral angles of 22.35 (10), 68.17 (10) and 42.01 (10) with the mean planes of the trimethoxyphenyl, chlorophenyl and difluorophenyl rings, respectively. A weak intramolecular C-H?? interaction occurs. In the crystal, molecules are linked into sheets lying parallel to the bc plane by C-H?O and C-H?N hydrogen bonds. The crystal packing also features weak C-H?? interactions.

4-(Morpholin-4-yl)-3-(trifluoro-meth-yl)-benzonitrile
(2011) Fun, H.-K.; Asik, S.I.J.; Kumar, R.; Isloor, A.M.; Shivananda, K.N.
In the title benzonitrile compound, C 12H 11F 3N 2O, an intra-molecular C - H?F hydrogen bond generates an S(7) ring motif. The trifluoro-methyl group is disordered over two orientations with a refined occupancy ratio of 0.549 (16):0.451 (16). The morpholine ring adopts a chair conformation. The benzene ring and mean plane of the morpholine ring make a dihedral angle of 58.04 (10) with each other. In the crystal, mol-ecules are connected by inter-molecular C - H?F and C - H?O inter-actions to form R 2 2(8) ring motifs. These inter-actions also link the mol-ecules into chains parallel to the [10[ direction. Fun et al. 2011.
