Molecular tectonics: from a binuclear metallamacrocycle to a 1D isostructural coordination network based on tetracyanomethyl[1.1.1.1]metacyclophane and a silver cation

Depending on the anion ($\mathrm{NO_3^-}$ or $\mathrm{BF_4^-}$) and stoichiometry, the combinations of [1.1.1.1]metacyclophane adopting a blocked 1,3-alternate conformation and bearing four cyanomethylene groups with silver cations under self-assembly conditions lead to the formation of either a 1D coordination network or a discrete binuclear metallomacrocycle.
