Abstract

Abstract: The reaction of thorium(IV) nitrate with cucurbit[6]uril (CB6) in the presence of perrhenic acid in water gives the complex [Th(NO3 )(H2 O)8 ][(ReO4 )(CB6)](ReO4 )2 · 3H2 O (1 ). Aquated cations are held at both CB6 portals by ion–dipole and hydrogen‐bonding interactions, and one of the ReO4 – 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. Abstract : Aquated thorium cations are held at both portals of cucurbit[6]uril (CB6) by ion–dipole and hydrogen‐bonding interactions, one perrhenate anion being included in the macrocycle cavity. Hirshfeld surfaces are used to visualize short contacts between the species present.
