摘要
Reactions of divalent metal salts with 4,4-oxybis(N-(pyridine-4-yl)-benzamide), L, and naphthalene-1,4-dicarboxylic acid (1,4-H 2 NDC) in various solvents gave [Zn(L)(1,4-NDC)·H 2 O] n , 1, [Cd(L)(1,4-NDC)(H 2 O)·MeOH] n , 2, and [Co(L)(1,4-NDC)(H 2 O) 0.5 ·MeOH] n , 3, which have been structurally characterized. Complexes 1–3 show eight-fold interpenetrating frameworks with the dia topology, which exhibit porosities substantiated by CO 2 adsorption, whereas 1 and 2 manifest stability in aqueous environments and show high selectivity toward sensing of mesitylene molecules and Fe 3+ ions with low detection limits and good reusability up to five cycles.
