Recently, three groups, including our group, reported several organic-inorganichybrids composed of barrel-like cyclic host molecules (cucurbit[n]uril) and polyoxovanadates. This review mainly gives a brief summary of our preparation and the structures of four novel organic-inorganic hybrids i.e., two 2D ladder-like structures, a 1:2 complex and a 1D infinitely linear chain from the reactions of decamethylcucurbit[5]uril (MeCuc5) and decavanadate salts (M6[V10O28], M= Na+ or NH4+). Carbonyl oxygen atoms at the portals of MeCuc5 molecules coordinate to cations at the center or corner of the portals and the resulting cationic organic species and decavanadate anions interact though electrostatic interaction and hydrogen bonds in the crystals.
