Fig. 2. Thermal ellipsoid plot (at the 50% probability level) of the solid-state structure of 3, an Am(iii) dimer. Hydrogen atoms have been omitted for clarity, and tBu groups are shown as ball-and-stick depictions also for clarity. Atom labelling has been shown only for unique hetero atoms and the symmetry-equivalent bridging N, O atoms, and the unique Am center. Symmetry operations: −X, 2 − Y, 2 − Z.
