Cover Picture Melanie Schnell, Jens-Uwe Grabow,* Jos L. Alonso,* Emilio J. Cocinero, Alberto Lesarri, M. Eugenia Sanz, and Juan C. L#pez Microsolvation of glycine has been studied by combining impulse supersonic-jet Fourier-transform microwave spectroscopy with laser ablation and the structure of the monohydrated complex derived from rotational spectra. Combining this method with theoretical considerations enables the internal dynamics of multiple large-amplitude motions, such as in (CH3)3XCl (X ¼ Si, Ge, Sn), to be revealed. For more details, see the Communications by J.-U. Grabow and J. L. Alonso and co-workers on pages 3465 and 3471 ff. Nanoparticle Synthesis Inorganic nanocrystals with size- and shape-dependent properties are excellent building blocks for functional nanosystems. Recent developments in the shapecontrolled synthesis of colloidal nanocrystals are described by J. Cheon et al. in their Review on page 3414 ff. Molecular Recognition Four methyl lactate molecules with alternating configurations cluster through hydrogen bonds to form a structure unfavored for homoconfigurational tetramers. See the Communication by M. A. Suhm and co-workers on page 3440 ff., for further details. Main-Group Hydrides Reaction of a calcium amide with phenylsilane leads to the ready formation of a molecular calcium hydride. S. Harder and J. Brettar describe in the Communication on page 3474 ff. their approach to this new class of compound.
