Soft skin, hard core
is the basic principle for the formation of a nano-alloy from molecular precursors. The
co-hydrogenolysis of ruthenium complexes in presence of GaCp* gives the isolable
key intermediate [Ru2(Ga)(GaCp*)7(H)3] featuring a substituent-free bridging gallium
atom. From this “embryonic” species Ru/Ga phases are formed by complete cleavage
of the protective Cp* shell (depicted as an eggshell in the Cover picture), as described
by R. A. Fischer et al. in their Communication on page 3872 ff.
History of Science
In their Essay on page 3744 ff., B. Kahr, D. Viterbo, et al. examine the work of
Eligio Perucca on the enantioselective adsorption of a racemic mixture to a chiral
crystal and his relationship to Primo Levi.
Vibrational Spectroscopy
The fundamental principles of coherent multidimensional vibrational spectroscopy
and its application to biomolecules are presented by S. Mukamel et al. in their
Review on page 3750 ff. Particular attention is paid to spectral simulation techniques.
Polyoxometalates
Crystalline solids can be tailored using molecular building blocks. In the
Communication on page 3782 ff., M. Sadakane, W. Ueda, and co-workers use a
pentagonal polyoxomolybdate unit as the basis for an orthorhombic Mo-V-Sb
oxide.
