In the title compound, [Ag2(C12H12N2)(C21H15N3)2](CF3SO3)2, the AgI atom is coordinated by three N atoms of one 4′-phenyl-2,2′:6′,2′′-terpyridine (phtpy) ligand and one pyridyl N atom of the 1,2-bis(4-pyridyl)ethane (bpe) ligand, displaying a distorted square-planar geometry. Two AgI atoms are bridged by one trans-bpe ligand, generating a dinuclear cation. The dinuclear cation is located on a centre of inversion, which is in the middle of the ethylene fragment of the bpe ligand. In the crystal, the pyridyl rings of neighboring dinuclear units are stacked by π–π interactions with centroid–centroid distances of 3.667 (2) and 3.835 (2) Å. The F and O atoms of the CF3SO3− anions are involved in intermolecular C—H...F and C—H...O hydrogen-bonding interactions, respectively, with –CH groups from the phtpy ligands.
