Fig. 3: Molecular structure of UN@Cs(6)-C82 measured with single-crystal X-ray diffraction at variable temperatures from 100 K to 273 K.
From: A charged diatomic triple-bonded U≡N species trapped in C82 fullerene cages

The displacement parameters are shown at the 20% probability level for the encapsulated UN cluster. The structures are drawn from the chosen specific direction of the crystal to compare the dynamics of the UN@Cs(6)-C82. Color code: blue for N, and red for U.
