In the binuclear title complex, [Ag(2)(C(31)H(22)N(4)O)(2)](ClO(4))(2)·2C(3)H(7)NO, the Ag(I) atom is penta-coordinated by three N atoms from the tridentate chelating terpyridyl group and by one N atom and one O atom from the quinolin-8-yl-oxy group in a distorted square-pyramidal geometry with the O atom at the apical position. The centrosymmetric complex cation involves intra-molecular π-π stacking inter-actions [centroid-centroid distance = 3.862 (4) Å] between the central pyridine and benzene rings. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds result in the formation of a supra-molecular network.
