[μ-1,2-Bis(4-pyrid­yl)ethane-κ(2) N:N′]bis­[(4′-phenyl-2,2′:6′,2′′-terpyridine-κ(3) N,N′,N′′)silver(I)] bis­(trifluoro­methane­sulfonate)

In the title compound, [Ag(2)(C(12)H(12)N(2))(C(21)H(15)N(3))(2)](CF(3)SO(3))(2), the Ag(I) 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 Ag(I) 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 CF(3)SO(3) (−) anions are involved in inter­molecular C—H⋯F and C—H⋯O hydrogen-bonding inter­actions, respectively, with –CH groups from the phtpy ligands.
