Macrocyclic-ligand Induced Synthesis of Aryl Ethynides with Divergent Silver(I) Clusters

Two structurally characterized metal-cluster-centered supramolecular architectures named [Ag-8(1,2-(CC)(2)-C6H4)(Py[6])(CF3CO2)(6)]2.5MeOH (1) and [Ag-12(1,2,4,5-(CC)(4)C6H2)(Py[6])(2)(CF3SO3)(8)]4MeOH3H(2)O (2) are synthesized through the interaction with a bowl-shaped macrocyclic ligand Py[6]. Particularly, two dissimilar silver(I) clusters are resulted in 2 within the structure under the influence of the macrocyclic ligand Py[6]. Such dissimilarity of the silver(I) cluster is also reflected on the structural and photophysical differences between 1 and 2.
