In the title salt, [Ag(C(9)H(8)N(6))(2)]NO(3), the central Ag(I) atom is linearly coordinated by the N atoms [171.97 (8)°] from two 1-[(benzimidazol-1-yl)meth-yl]-1H-1,2,3,4-tetra-zole ligands. The benzimidazole rings in adjacent mol-ecules are parallel with an average inter-planar distance of 3.461 Å; adjacent mol-ecules are linked through N-H⋯O hydrogen bonds into a linear chain along the b-axis direction.
