A one-dimensional Ag(I) coordination polymer: catena-poly[[[[N′-(4-cyano­benzyl­idene)nicotinohydrazide]silver(I)]-μ-N′-(4-cyano­benzyl­idene)nicotino­hydrazide] trifluoro­methane­sulfonate]

In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3)}(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—H⋯O hydrogen bonds. In addition, there are relatively short Ag⋯O contacts of 2.723 (3) Å, which connect the chains into a three-dimensional structure.
