A novel hydrogen-bonded duplex made up of water molecules and halide ions in the sandwich inclusion structures of (C10H8N3S)(+)center dot X center dot 2H(2)O [X=Cl-, Br-]
The X-ray crystal structures of thiabendazolium halide dihydrates (C10H8N3S)(+). X . 2H(2)O [X = Cl-, Br-] 1, 2 reveal a novel hydrogen-bonded duplex consisting of alternate edge-sharing (H2O . X)(2) quadrilaterals and (2H(2)O . X)(2) hexagons; notably these duplexes exist as host lattices and sandwich thiabendazole molecules into two different supramolecular architectures by similar N ... X and N ... O hydrogen bonds.
