    The asymmetric unit of the title compound, C(20)H(28)N(2)O(6)S(2), contains one half-mol-ecule, related to the other half by a twofold rotation axis. The two aromatic rings of the mol-ecule make a dihedral angle of 50.91 (7)°. The O-CH(2)-CH(2)-O and N-CH(2)-CH(2)-O fragments both adopt gauche conformations, with torsion angles of 76.0 (4) and 70.4 (3)°, respectively. In the crystal, adjacent mol-ecules are linked through N-H⋯O hydrogen bonds into chains along the a-axis direction. The chains are further connected via C-H⋯O inter-actions into a two-dimensional supra-molecular network in the ac plane.

    In the title compound, C(9)H(14)N(2)O(2), the imidazole ring and the acetate O-C=O plane make a dihedral angle of 80.54 (12)°. In the crystal, mol-ecules are connected via pairs of C-H⋯O hydrogen bonds, forming centrosymmetric dimers.

    The centroid of the central aromatic ring of the title mol-ecule, C(24)H(22)O(4), is located on an inversion center. The dihedral angle between the central and terminal benzene rings is 75.00 (7)°. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds into chains along [121]. The chains are connected into layers via C-H⋯π inter-actions.

    Acta Crystallogr Sect E Struct Rep Online, 2011 Dec 1;67(Pt 12):o3140.
    PMID: 22199668 DOI: 10.1107/S1600536811045041
    In the title compound, C(24)H(22)O(4), the centroid of the central benzene ring lies on a special position of 2/m site symmetry, while the terminal aromatic rings are located on a mirror plane. The central and terminal benzene rings are perpendic-ular to each other. In the crystal, the mol-ecules are connected via C-H⋯O hydrogen bonds into a three-dimensional polymeric structure. The network is further consolidated by a C-H⋯π inter-action.

    PMID: 22220033 DOI: 10.1107/S1600536811042528
    The asymmetric unit of the title compound, C(24)H(22)O(4), contains one half-mol-ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent mol-ecules are linked through C-H⋯O inter-actions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via π-π inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276 (6) Å].

    Several new substituted sulfonamide compounds were synthesized and their structures were confirmed by ¹H-NMR, ¹³C-NMR, FT-IR, and mass spectroscopy. The antibacterial activities of the synthesized compounds were screened against standard strains of six Gram positive and four Gram negative bacteria using the microbroth dilution assay. Most of the compounds studied showed promising activities against both types of bacteria.

    PMID: 21837205 DOI: 10.1107/S1600536811024664
    The title mol-ecule, C(26)H(30)O(9)S(3), adopts an extended conformation whereby two approximately parallel benzene rings [dihedral angle = 8.32 (10)°] are orientated in opposite directions along the pseudo-threefold axis through the central quaternary C atom, while a third ring occupies a position mid-way and face-on to these rings [dihedral angles = 82.28 (10) and 78.81 (7)°]. The crystal packing is dominated by C-H⋯O contacts and π-π inter-actions [ring centroid distance = 3.6902 (12) Å].
