Bis[N′-(3-cyanobenzylidene)isonicotinohydrazide-κN]silver(I) trifluoromethanesulfonate

Abstract

In the title compound, [Ag(C14H10N4O)2]CF3SO3, two N atoms from two independent pyridyl rings of two N′-3-cyanobenzylideneisonicotinohydrazide ligands coordinate to the unique AgI ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag...N interactions, with Ag...N separations of 2.877 (2) and 3.314 (2) Å. On the other hand, one CF3SO3− anion interacts with hydrazone groups of two neighbouring ligands via N—H...O hydrogen bonds. These weak intermolecular interactions contribute to the formation of supramolecular chains. In addition, there are Ag...O interactions [2.787 (2) Å] between Ag and O atoms from adjacent chains.
