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