Zeolite-supported transition-metal catalysts are of importance in the petrochemical industry. However, the fabrication and characterization of well-defined systems remains a challenge. In their Communication on page 574 ff., B. C. Gates, J. F. Haw, and co-workers present computational and experimental evidence that the rhodium complex {Rh(C2H4)2} supported on zeolite Y is a single-site catalyst with a uniform structure. The cover picture shows the rotation of the ethylene ligands about the Rh+ center (green sphere).
