Connecting clusters: A new class of approximately 3.4 nm sized inorganic–organic–inorganic hybrids was synthesized by covalent functionalization of V3‐capped Wells–Dawson‐type clusters with linear bis(Tris) ligands (see scheme; TBA=nBu4N+). These hybrids were characterized using single‐crystal XRD and ESI‐MS techniques. Dynamic light scattering studies revealed the surfactant properties of these compounds, which lead to the formation of supramolecular vesicles in solutions.

Verknüpfte Cluster: Eine neue Klasse anorganisch‐organisch‐anorganischer Hybride mit Größen von etwa 3.4 nm wurde durch kovalente Funktionalisierung V3‐überdachter Wells‐Dawson‐Cluster mit linearen Bis(tris)‐Liganden hergestellt (siehe Schema; TBA=nBu4N+) sowie röntgenkristallographisch und mit ESI‐MS charakterisiert. Die Verbindungen weisen Tensideigenschaften auf (dynamische Lichtstreuung) und bilden in Lösung supramolekulare Vesikel.

Tungsten I 5700 Synthesis of Modular "Inorganic-Organic-Inorganic" Polyoxometalates and Their Assembly into Vesicles. -Compounds (II) and (III) which are approximately 3.4 nm long represent the first examples of inorganic-organic-inorganic "dumbbell" hybrids based on functional Wells-Dawson-type clusters. They are characterized by ESI-MS, IR, and NMR spectroscopy. (II)·20MeCN crystallizes in the monoclinic space group C2/c with Z = 4 (single crystal XRD). It contains two {P2V3W15O62} clusters linked by a bis(triol) ligand. Both compounds (II) and (III) are amphiphilic, acting like surfactants in solution. These compounds are capable of undergoing a remarkable supramolecular selfassembly process in acetone/water mixtures, which leads to the formation of vesicles. -(PRADEEP, C. P.; MISDRAHI, M.
