In the title centrosymmetric binuclear AgI complex, [Ag2(C12H10N4)2](ClO4)2, each AgI center is two-coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 1-(2-pyridylmethyl)-1H-benzotriazole (L) ligands. This forms a unique box-like cyclic dimer with an intramolecular Ag⋯Ag separation of 4.479 (2) Å. Intermolecular C—H⋯O hydrogen-bonding interactions, involving uncoordinated ClO4
− ions, link the binuclear units, forming a two-dimensional network parallel to (10).
