Abstract: In the title compound, {[Ag(C₁₄H₁₀N₄O)₂]CF₃SO₃}_n, the unique Ag^I ion is coordinated by two N atoms from two pyridine rings of two independent N'-(4-cyanobenzylidene)nicotinohydrazide ligands and one N atom of a carbonitrile group of a symmetry-related N'-(4-cyanobenzylidene)nicotinohydrazide ligand, forming a distorted T-shaped coordination environment. One of the independent ligands acts as a bridge connecting Ag^I ions, forming chains along the a axis. In the crystal structure, two neighbouring antiparallel chains are connected through N-HO hydrogen bonds. In addition, there are relatively short AgO contacts of 2.723 (3) Å, which connect the chains into a three-dimensional structure.
