The review surveys new data on the directed construction of supramolecular organic-inorganic compounds from macrocyclic cavitand cucurbit [6]uril (C 36 H 36 N 24 O 12 ) 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. CUCURBIT[N]URILSCucurbit[n]urils are organic macrocyclic cavitands synthesized by condensation of formaldehyde with glycoluril [1-6]. The cucurbit[n]uril molecules resemble in shape a barrel containing two identical carbonile fringed portals (Chart 1). Having a large inner cavity, cucurbit[n]urils can serve as hosts to form inclusion compounds with guest molecules of suitable size [3,4,[7][8][9]. Due to the presence of polarized carbonyl groups, cucurbit[n]urils can also form complexes and hydrogen-bonded supramolecular adducts with mono-and polynuclear aqua complexes.Cucurbituril with composition C 36 H 36 N 24 O 12 (cucurbit[6]uril, Q6) consisting of six methylenelinked glycoluril fragments has been studied the most. This compound is the first example of cucurbiturils, and almost a century has passed since its first synthesis by Behrend [1]. The chemical nature and structure of cucurbit[6]uril had been unknown until 1981, when full characterization was reported by Freeman [2]. The dimensions of the inner cavity of Q6 (the height is 6 Å and the inner diameter is 5.5 *Plenary lecture presented at the

The cluster aqua complexes [Mo 3 (MCl)Q 4 (H 2 O) 9 ] 3+ (M = Pd or Ni) in hydrochloric acid solutions induce isomerization of the hydrophosphoryl compounds (HO) 2 P(O)H, (HO)P(O)H 2 , PhP(O)(OH)H, and Ph 2 P(O)H into the hydroxo tautomers P(OH) 3 , HP(OH) 2 , PhP(OH) 2 , and Ph 2 P(OH), which are stabilized by coordination of the phosphorus atom to the Pd or Ni atoms. The reactions were studied by 31 P NMR and UV Vis spectroscopy. The kinetics of the reactions of phosphorous acid with [Mo 3 (PdCl)Q 4 (H 2 O) 9 ] 3+ was investigated by spectropho tometry. The [Mo 3 (Pd(PhP(OH) 2 ))S 4 (H 2 O) 2 Cl 7 ] 3-complex was isolated as a supramolecular adduct with cucurbit[8]uril, and the [Mo 3 (Ni(P(OH) 3 ))S 4 (H 2 O) 8 Cl] 3+ complex was isolated as an adduct with cucurbit[6]uril. The structures of both compounds were established by X ray diffraction analysis.

“…It has previously been reported that the Ni heterometal in the Mo 3 NiS 4 cluster presents a unique and exceptional reactivity and is able to coordinate different ligands. It shows a great tendency to coordinate soft ligands19,30,33,34 containing S, P, and As donors and π acceptor ligands such as alkenes, alkynes, and CO as well as sulfur ligands from neighboring clusters. The isolation and full characterization of compound 1 is the first example in which a trinuclear Mo 3 cluster acts as a ligand for the Mo 3 NiS 4 cluster and it provides a unique opportunity to isolate the first Mo 3 S 6 cluster.…”
