Metallosupramolecules of pillar[5]-bis-trithiacrown including a mercury(II) iodide ion-triplet complex

Abstract

A combination of pillar[5]-bis-trithiacrown (L) and mercury(II) halides afforded a monomer complex (Cl--form), a 1-D coordination polymer (Br--form) and a supramolecular ion-triplet complex [(I center dot Hg center dot I)@L] (I--form). In the ion-triplet complex, the host encapsulates the (I--Hg2+-I-) entity via Hg2+center dot center dot center dot pi and C-H center dot center dot center dot I- interactions, reflecting geometrical complementarity.
