Abstract: In the title compound, [Ag(C₁₄H₁₀N₄O)₂]CF₃CO₂, the Ag^I ion is coordinated by two N atoms of the pyridine rings of two N'-(3-cyanobenzylidene)isonicotinohydrazide ligands in a nearly linear geometry. In the crystal structure, a combination of close contacts formed via AgN interactions [AgN = 3.098 (2) and 3.261 (2) Å] from symmetry-related molecules and intermolecular N-HO hydrogen bonds between CF₃CO₂^- anions and the hydrazone groups of two ligands give rise to chains. Furthermore, there are AgO interactions with a separation of 2.765 (2) Å between chains. The F atoms of the CF₃CO₂^- anion are disordered over two sites with refined occupancies of 0.593 (5) and 0.407 (5).
