    2-(4-Bromo-phen-yl)-2-oxoethyl 4-bromo-benzoate
    (2011) Fun, H.-K.; Arshad, S.; Garudachari, B.; Isloor, A.M.; Satyanarayan, M.N.
    The asymmetric unit of the title compound, C 15H 10Br 2O 3, consists of three crystallographically independent mol-ecules (A, B and C). The phenyl rings in mol-ecules A, B and C make dihedral angles of 6.1 (3), 3.2 (2) and 54.6 (2)° to each other, respectively. In the crystal, mol-ecules are linked into two-dimensional layers parallel to the ab plane by inter-molecular C - H?O hydrogen bonds. The crystal structure is further stabilized by C - H?? inter-actions. The studied crystal is an inversion twin, the refined ratio of the twin components being 0.128 (8):0.872 (8). © Fun et al. 2011.

    2-(4-Chloro-phen-yl)-2-oxoethyl 2,4-di-fluoro-benzoate
    (2011) Fun, H.-K.; Arshad, S.; Garudachari, B.; Isloor, A.M.; Satyanarayan, M.N.
    The asymmetric unit of title compound, C 15H 9C lF 2O 3, consists of two crystallographically independent mol-ecules. The dihedral angle between the two terminal benzene rings in one mol-ecule is 7.92 (14)°, while that in the other mol-ecule is 73.50 (16)°. In the crystal, mol-ecules are stacked into columns along the b axis by inter-molecular C - H?O hydrogen bonds. A ?-? inter-action with a centroid-to-centroid distance of 3.747 (2) Å further stabilizes the crystal structure. © Fun et al. 2011.

    2-(4-Bromo-phen-yl)-2-oxoethyl 4-chloro-benzoate
    (2011) Fun, H.-K.; Yeap, C.S.; Garudachari, B.; Isloor, A.M.; Satyanarayan, M.N.
    The asymmetric unit of the title compound, C 15H 10BrClO 3, consists of three crystallographically independent mol-ecules. The dihedral angles between the benzene rings in the three mol-ecules are 68.8 (2), 0.7 (3) and 66.1 (2)°. In the crystal, the three independent mol-ecules are inter-connected by C - H?O hydrogen bonds, leading to isolated trimers. © Fun et al. 2011.
