Solid-state assembly of a resorcin[6]arene in twin molecular capsules

The solid state structures of a resorcin[6]arene macrocycle crystallized in two different forms are here reported. In both instances, the molecule adopts a pinched cone conformation very similar to that of p-tert-butylcalix[6]arene. In one case, the resorcin[6]arene macrocycle self-assembles in a molecular capsule able to host toluene and ethyl acetate solvent molecules.
