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 - 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-HF and C-HO hydrogen-bonding interactions, respectively, with -CH groups from the phtpy ligands.
