The benzimidazole compounds and benzoannulated cyclic benzimidazole analogues, such as benzimidazo[1,2-a]quinolines, are a part of our wider investigation on biologically active compounds, potential antitumor drugs. Here, we present the synthesis of two compounds, [2-(1H-benzimidazol-2-yl)-3-(4-bromophenyl)-acrylonitrile, 5] and [2-bromo-benzimidazo[1,2-a]quinoline-6-carbonitrile, 7] and their crystal...
The series of compounds of the general formulae HgX2(tzdtH) and HgX2(tzdtH)2 (X = Cl, Br, I; tzdtH = 1,3-thiazolidine-2-thione) have been prepared, as well as Hg(tzdt)2. IR, 1H, and 13C NMR spectral data of the complexes indicate thione donation, which is confirmed by the crystal structure analyses of [HgBr2(tzdtH)]2, [HgI2(tzdtH)]2, and HgI2(tzdtH)2. The structures of [HgBr2(tzdtH)]2 and [HgI2(tzdtH)]...
