Cover Picture: A Synthetic Breakthrough into an Unanticipated Stability Regime: A Series of Isolable Complexes in which C 6 , C 8 , C 10 , C 12 , C 16 , C 20 , C 24 , and C 28 Polyynediyl Chains Span Two Platinum Atoms (Chem. Eur. J. 25/2006)

Record‐breaking PtC x Pt polyynes have been synthesized, isolated, and fully characterized by J. A. Gladysz et al.; the results are reported in their Full Paper on page 6486 ff. The spectroscopic and structural properties of PtC x Pt establish a number of interesting chain‐length effects, which are becoming increasingly well defined for polyynes.
