摘要

A mixed-ligand Ag(I) coordination polymer {[Ag₂(bpe)₂(H₂O)₂](chd)路5H₂O}_n (1) (bpe = 4,4鈥?bipyridylethylene, H₂chd = 1,4-cyclohexanedicarboxylic acid), has been synthesized and structurally characterized. Complex 1 exhibits a three-dimensional (3-D) supramolecular sandwich architecture that is composed of cationic chains of Ag(I) ions and bpe ligands, alternating with anionic sheets in which uncoordinated chd^{2 鈭?/sup> anions and water molecules form a 2-D hydrogen-bonded network. An odd-numbered (H₂O)₇ cluster is trapped inside the water-chd aggregation. The discrete water heptamer consists of a puckered pentameric core and two pendent water molecules and structurally shows similarity to the simple hydrocarbon (1,1)-dimethylcyclopentane.}
