Structure directing role of a tridentate ligand in a two-dimensional Ag(I) network

The hydrothermal reaction of silver nitrate with 4,4′-dipyridylamine (Hdpa) yields a new Ag(I) two-dimensional network material, [Ag(dpa)]. The structure is constructed from trigonal Ag(I) sites bound to two nitrogen donors from adjacent dpa− ligands and the central deprotonated nitrogen of the dpa− ligand.
