Each of the ions in the title salt, [Ag(C6H6N2O)2]ClO4, is completed by the application of crystallographic twofold symmetry. The AgI atom is coordinated by two pyridine N atoms in an almost linear fashion [N—Ag—N = 170.0 (2)°], with the T-shaped coordination geometry being completed by a weakly associated perchlorate-O atom. Supra­molecular zigzag chains along [100] mediated by O—H⋯N hydrogen bonds [as parts of R22(6) loops] feature in the crystal packing. The perchlorate O atoms are disordered over two sets of sites in a statistical ratio.
