The later actinides (Am-Cf) have been significantly underexplored in comparison to the early actinides because of their similarities to the lanthanides. This area of research has recently gained interest because of the need to separate americium and curium from lanthanides in spent nuclear fuel. In lanthanides and later actinides, coordination and redox chemistry dominate. Albeit the later actinides core <i>f</i>-orbitals are much shielded like the lanthanides, the slight difference in this shielding allows for small differences to be observed. By utilizing non-aqueous conditions, the extents of these differences can be expanded from pure aqueous media. Herein, the cooridination and redox differences between the lanthanides and later actinides are observed through solid state, electrochemical, and computational analyses in non-aqueous and air-free environments.
