Cover Picture: Direct Observation of Hydrogen Molecules Adsorbed onto a Microporous Coordination Polymer (Angew. Chem. Int. Ed. 6/2005)
Fundamental structural information on hydrogen molecules adsorbed in nanochannels is required for the rational synthetic design of novel metal–organic porous materials as hydrogen-storage materials. The cover picture shows the charge-density distribution of hydrogen molecules adsorbed in the nanochannels of a copper coordination polymer. The hydrogen molecules are located in the pocket cavities of the suitably sized nanochannels. More details can be found in the Communication by Y. Kubota et al. on page 920 ff.

The 60th anniversary of the publication of Woodward's synthesis of quinine is marked by T. S. Kaufman and E. A. Rúveda in their Review on page 854 ff. An overview is given of the history of quinine, from its discovery to the three modern total syntheses.
The fabrication of patterns of magnetic bits on a polymer surface is described by J. Veciana, F. Biscarini, and co-workers in their Communication on page 888 ff. This approach yields a system for permanent information storage with magnetic readout.
G. Christou and co-workers report on one of the rare single-molecule magnets with a cyclic structure on page 897 ff. The compound, a Mn12 cluster, has a high ground-state spin of 7.
