52_11i/2013Inside Cover: A Rare Uranyl(VI)–Alkyl Ate Complex [Li(DME)1.5]2[UO2(CH2SiMe3)4] and Its Comparison with a Homoleptic Uranium(VI)–Hexaalkyl (Angew. Chem. Int. Ed. 11/2013)

A rare uranyl–alkyl “ate” complex was prepared for comparison with a homoleptic UVI–hexaalkyl. In their Communication on page 3259 ff., P. Hrobárik, T. Hayton, et al. demonstrate that both complexes feature unprecedented high-frequency methylene 13C shifts, consistent with large spin-orbit effects. Relativistic calculations show that the cause is significant f-orbital involvement in σ-bonding.
