%X In the title compound, {[Ag(C14H10N4O)2]CF3SO3}n, the unique AgI ion is coordinated by two N atoms from two pyridine rings of two independent N¡ä-(4-cyanobenzylidene)nicotinohydrazide ligands and one N atom of a carbonitrile group of a symmetry-related N¡ä-(4-cyanobenzylidene)nicotinohydrazide ligand, forming a distorted T-shaped coordination environment. One of the independent ligands acts as a bridge connecting AgI ions, forming chains along the a axis. In the crystal structure, two neighbouring antiparallel chains are connected through N¡ªH...O hydrogen bonds. In addition, there are relatively short Ag...O contacts of 2.723 (3)  , which connect the chains into a three-dimensional structure.
