Poly[[bis­[μ(2)-N,N′-bis­(2-pyridyl­meth­yl)oxalamide-κ(4) N,O:N′,O′][μ(2)-N,N′-bis­(2-pyridyl­meth­yl)oxalamide-κ(2) N:N′]disilver(I)] bis­(trifluoro­methane­sulfonate)]

The asymmetric unit of the title salt, [Ag(C(14)H(14)N(4)O(2))(1.5)](CF(3)SO(3)), comprises a Ag(+) cation, three half-mol­ecules of N,N′-bis­(2-pyridyl­meth­yl)oxalamide (each of which is dis­posed about a centre of inversion) and a trifluoro­methane­sulfonate anion. Distinct coordination modes are found for the bridging ligands, i.e., a μ(2),κ(2)-bridging mode involving pyridine N atoms for one ligand, and a μ(2),κ(4)-bridging mode, employing both pyridine N and amide O atoms for the remaining ligands. The Ag(+) cations, which are in a distorted square-pyramidal coordination, and the ligands combine to form a two-dimensional array parallel to (101); these arrays are connected into a three-dimensional structure by trifluoro­methane­sulfonate anions via N—H⋯O, C—H⋯O, and C—F⋯O inter­actions.
