Mono- and polynuclear aqua complexes and cucurbit[6]uril: Versatile building blocks for supramolecular chemistry

O. A. Gerasko, M. N. Sokolov, and V. P. Fedin

Nikolaev Institute of Inorganic Chemistry, Siberian Branch of the Russian Academy of Sciences, Ac. Lavrentiev Avenue 3, 630090 Novosibirsk, Russia

Abstract: The review surveys new data on the directed construction of supramolecular organic�inorganic compounds from macrocyclic cavitand cucurbit[6]uril (C₃₆H₃₆N₂₄O₁₂)and mono- and polynuclear aqua complexes. Due to the presence of polarized carbonyl groups, cucurbit[6]uril forms strong complexes with alkali, alkaline earth and rare-earth metal ions, and hydrogen-bonded supramolecular adducts with cluster and polynuclear aqua complexes of transitional metals. A wide variety of supramolecular compounds and their unique structures are described.
