Graphical Abstract

Insights into the electronic properties of actinide ions can be obtained by using X-ray magnetic circular dichroism spectroscopy. In their Communication on page 15650 ff., K. S. Pedersen, R. Clérac, and co-workers present the first structurally characterized hexafluorido complex of a tetravalent actinide ion, [UF6]2–. Its non-magnetic ground state results from an almost perfect cancellation of spin and orbital magnetic moments, which are virtually identical in magnitude but opposite in sign.
