In the title centrosymmetric binuclear Ag(I )complex, [Ag(2)(C(12)H(10)N(4))(2)](ClO(4))(2), each Ag(I) center is two-coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 1-(2-pyridylmeth-yl)-1H-benzotriazole (L) ligands. This forms a unique box-like cyclic dimer with an intra-molecular Ag⋯Ag separation of 4.479 (2) Å. Inter-molecular C-H⋯O hydrogen-bonding inter-actions, involving uncoordinated ClO(4) (-) ions, link the binuclear units, forming a two-dimensional network parallel to (10).
