Cover Picture: A Molybdenum Crown Cluster Forms Discrete Inorganic–Organic Nanocomposites with Metalloporphyrins (Angew. Chem. Int. Ed. 46/2004)
A generous host describes the fully inorganic doughnut-shaped polyoxometalate crown cluster illustrated in the cover picture which has a 2.3-nm-wide and 1.3-nm-deep nanoscopic cavity and serves as a novel host for three metalloporphyrin molecules that contain 3- or 4-aminophenyl groups. A. Tsuda, T. Kawai, T. Aida, and co-workers describe in their Communication on page 6327 ff. how this new organic/inorganic hybrid complex forms through multiple hydrogen-bonding interactions.
