Abstract

The asymmetric unit of the title salt, [Ag(C14H14N4O2)1.5](CF3SO3), 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 μ2,κ2-bridging mode involving pyridine N atoms for one ligand, and a μ2,κ4-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.
