Abstract

Concentric circles: The interplay of metal-coordination geometry, dipolar interactions, and hydrogen bonding orchestrate the complex supramolecular assembly of three or four neutral metallacycles of [{cis-Cu(μ-OH)(μ-pz)}n] n=6, 8, 9, 12, 14, that encapsulate anions (encapsulated SO42− depicted; Cu blue; O red; N light blue; C black; S yellow) by multiple hydrogen bonding. This orchestration of several chemical forces for the accomplishment of a specific task imitates the strategies of Nature for similar purposes.
