Encapsulation of a (H3O2)− unit in the aromatic core of a calix[6]arene closed by two Zn(ii) ions at the small and large rims†
Abstract
The coordination of a first Zn(II) ion to a calix[6]arene presenting three imidazolyl arms at the small rim and three aniline moieties at the large rim allows the binding of a second Zn(II) ion while hosting a (H3O2)− unit in the aromatic cavity.
