Fig. 2

a Asymmetric unit of U-CB[8]-MPyVB. Enlarged motifs (b, Motif 1 with orange-colored CB[8]; c, Motif 2 with green-colored CB[8]) showing different distances between C=C bonds in a pair of MPyVB ligands. d One-dimensional chain of U-CB[8]-MPyVB connected by a combination of supramolecular inclusion and coordination interactions (Color code: oxygen atom, red; carbon atom, gray; nitrogen atom, blue; uranium atom, yellow). e Packing mode of U-CB[8]-MPyVB in 3-D space and morphology of crystal structure (insert: optical photograph of a crystal of U-CB[8]-MPyVB).
