The reaction of thorium(IV) nitrate with cucurbit[6]uril (CB6) in the presence of perrhenic acid in water gives the complex [Th(NO 3 )(H 2 O) 8 ][(ReO 4 )(CB6)](ReO 4 ) 2 · 3H 2 O ( 1 ). Aquated cations are held at both CB6 portals by ion–dipole and hydrogen‐bonding interactions, and one of the ReO 4 – anions is included in the CB6 cavity. The packing displays columns of alternate cations and encapsulated anions. Hirshfeld surfaces are used to visualize short contacts between the species present.
