title: Bis[N'-(3-cyano-benzyl-idene)isonicotino-hydrazide-κN]silver(I) trifluoro-methane-sulfonate.
abstract: In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3), two N atoms from two independent pyridyl rings of two N'-3-cyano-benzyl-ideneisonicotinohydrazide ligands coordinate to the unique Ag(I) ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag⋯N inter-actions, with Ag⋯N separations of 2.877 (2) and 3.314 (2) Å. On the other hand, one CF(3)SO(3) (-) anion inter-acts with hydrazone groups of two neighbouring ligands via N-H⋯O hydrogen bonds. These weak inter-molecular inter-actions contribute to the formation of supra-molecular chains. In addition, there are Ag⋯O inter-actions [2.787 (2) Å] between Ag and O atoms from adjacent chains.
