Abstract: In the title centrosymmetric binuclear Ag^I complex, [Ag₂(NO₃)₂(C₁₂H₁₀N₄)₂], each Ag^I center is coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 2-(3-pyridylmethyl)-2H-benzotriazole (L) ligands, and an O atom of a coordinated NO₃^- anion in a distorted T-shaped geometry. This forms a unique box-like cyclic dimer with an intramolecular non-bonding AgAg separation of 6.327 (2) Å. Weak intermolecular AgO(nitrate) interactions [2.728 (4) and 2.646 (3) Å] link the binuclear units, forming a two-dimensional network parallel to (100). Intermolecular C-HO hydrogen-bonding interactions, involving the L ligands and the coordinated NO₃^- anions, link the sheets, forming a three-dimensional framework.
