Guilded Rafts can be formed by heterometallic clusters. In their Communication on
page 9663 ff., P. Braunstein, M. Bnard et al. describe the synthesis, structure, and
theoretical analysis of a unique series of 2D raft mixed-metal clusters of the type
{M[m]}n (M ¼ Cu, n ¼ 3; M ¼ Ag, Au, n ¼ 4; the bridging metalloligand [m] is
{MoCp(CO)3}). Intramolecular, metallophilic d10···d10 interactions occur in the n2triangular (M ¼ Cu) or n2-square (M ¼ Ag, Au) structures of the metal cores.
Grinding-Induced Chiral Resolution
The modern methods for transforming racemic conglomerates into enantiomerically
pure crystals have their origins in the studies by Ostwald. In the Minireview on
page 9600 ff., B. Kaptein et al. describe the development of the technique to its
current status.
Functionalization of Indoles
The indole system is ubiquitous in pharmaceuticals, and thus functionalization
methods have been eagerly sought. The Review by M. Bandini and A. Eichholzer on
page 9608 ff. reports the latest advances in the arylation and alkylation of indoles.
Fullerene Microspheres
In the presence of a porphyrin polymer, unmodified fullerene C60 self-assembles to
form complex superstructures in a controlled fashion. M. Takeuchi and X. Zhang
also propose a mechanism for this process in their Communication on page 9646 ff.
