[μ-1,2-Bis(4-pyridyl)ethane-κ2N:N′]bis-[(4′-phenyl-2,2′:6′,2"-terpyridine-κ3N,N′,N")silver(I)] bis(trifluoromethanesulfonate)

In the title compound, [Ag-2(C12H12N2)(C21H15N3)(2)]-( CF3SO3)(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 pi-pi interactions with centroid-centroid distances of 3.667 (2) and 3.835 (2) angstrom. The F and O atoms of the CF3SO3- anions are involved in intermolecular C-H center dot center dot center dot F and C-H center dot center dot center dot O hydrogen-bonding interactions, respectively, with -CH groups from the phtpy ligands.
