摘要

A flexible bis(pyridylcarbamate) receptor, 3-pyridyl-carbamic-acid-oxydi-1,2-ethanediylester (L2) and the anion complexes (1-3) of the doubly protonated ligand ([L2H2]2+) with Cl, S and Cla??? are reported. The binding modes of [L2H2]2+ with the anions in 1-3 in the solid state are established by X-ray single crystal diffraction. Compounds 1 and 3 feature intriguing anionic polymer fashions. In compound 1, two zigzag perchlorate-water chains are encapsulated in the 1D channel constructed by 2+2 (2[L2H2]2++2Cl) hydrogen-bonded macrocycles, while in 3 the chloride ions are trapped on the wall of the hydrogen-bonded 1D channel formed by two U-shaped ligands. For compound 2, the packing diagram displays a corrugated layer structure, with the sulphate ions and the water molecules located between the layers. Receptor L2 crystallises with perchlorate from the acid mixture HClO4, H2SO4 and HCl.View full textDownload full textKeywordsanion receptor, bis(pyridylcarbamate), hydrogen-bonded macrocycleRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10610270903509305
