In the development of silver(I) coordination polymers, the investigation of Ag^I coordination polymers using unsymmetrical dipyridyl ligands with nitrogen donor atoms on different positions in the two terminal pyridines still remains lacking. A self-assembly of the unsymmetrical ligand N-(pyridine-3-ylmethyl)pyridine-2-amine with the silver ion afforded an unusual sixteen-membered metallamacrocyclic dimer. In the crystal, various intermolecular interactions such as Ag···O, N–H···O C–H···O, and C–H···π interactions between the metallamacrocyclic dimers and the anions or the solvent molecules lead to the formation of a three-dimensional supramolecular network.
