✦ Synopsis

The title compound, Ag~2~(C~12~H~9~N~3~)~2~~2~, was prepared under hydrothermal conditions. The structure consists of binuclear complex cations and nitrate anions. The two Ag^I^ atoms, each in a geometry somewhat distorted from linear, are bridged by two 2-(3-pyridyl)benzimidazole ligands via pyridyl and imidazole N atoms, forming a centrosymmetric cyclic dimer. A three-dimensional network is constructed via N—H...O hydrogen bonds and weak Ag...O interactions [Ag...O = 2.686 (13)–2.847 (7) Å], as well as by offset π–π interactions between the pyridyl and imidazolyl rings with a nearest atom-to-atom distance of 3.40 (2) Å and a centroid-to-centroid distance of 4.06 (3) Å.
