Abstract: The cover picture shows a drawing of the solid-state structure of the new endohedral fullerene, Lu3N@C80, in crystalline Lu3N@C80⋅5(o-xylene). The fullerene cage is shown in yellow, the ordered o-xylene molecules in orange, and the atoms of the Lu3N unit connected in purple with black dashed lines outlining the positions of the Lu atoms. In this structure the fullerene cages are fully ordered, but the positions of the lutetium atoms are disordered with four different orientations existing inside the C80 cage. However, the Lu3N unit is nearly planar at each site. Only the major Lu3N site is illustrated in the cover drawing. Crystals of Lu3N@C80⋅5(o-xylene) and Sc3N@C80⋅5(o-xylene) are isomorphous, and despite the difference in ionic radii of Lu3+ (0.848 Å) and Sc3+ (0.68 Å), the dimensions of the C80 cage and of the Lu3N and Sc3N units within it are similar in these crystals. For details see the article by Balch et al. on p. 4528 ff.
