    3,3?-diethyl-1,1?-butylenedi[5(6)-methyl-benzimidazolium] diiodide dihydrate
    (Blackwell Munksgaard, 2003) Öztürk, S; Akkurt, M; Küçükbay, H; Okuyucu, N; Fun, HK
    The molecule of the title compound, C24H32N42+.2I(-).2H(2)O, possesses C-i symmetry with the inversion center at the midpoint of the central C-C bond between two benzimidazolium rings. In the crystal structure, the molecules stack along the a axis, forming channels occupied by a chain of I- ions bridged by water molecules via O-H...I hydrogen bonds.

    Synthesis and antibacterial activities of new bis-benzimidazoles
    (Ecv-Editio Cantor Verlag Medizin Naturwissenschaften, 2004) Küçükbay, H; Durmaz, R; Okuyucu, N; Günal, S; Kazaz, C
    Twenty bis-benzimidazole derivatives were synthesised by the reaction of benzimidazole with appropriate alkyl halides. The compounds synthesised were identified by H-1, C-13-NMR, FT-IR and micro analysis. All compounds studied in this work were screened for their in vitro antibacterial activity against standard strains; Enterococcus faecalis (ATCC 29212), Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853). Ten of the compounds were found effective to inhibit the growth of gram-positive bacteria (E. faecalis and S. aureus) at MIC (minimal inhibitory concentration) values between 50-400 mug/ml. Two of the compounds showed MIC values of 200 mug/ml against gram-negative bacteria (E. coli and P aeruginosa).
