Bis[N′-(3-cyanobenzylidene)isonicotinohydrazide]silver(I) trifluoroacetate
Abstract
In the title compound, [Ag(C14H10N4O)2]CF3CO2, the AgI ion is coordinated by two N atoms of the pyridine rings of two N′-(3-cyanobenzylidene)isonicotinohydrazide ligands in a nearly linear geometry. In the crystal structure, a combination of close contacts formed via Ag...N interactions [Ag...N = 3.098 (2) and 3.261 (2) Å] from symmetry-related molecules and intermolecular N—H...O hydrogen bonds between CF3CO2− anions and the hydrazone groups of two ligands give rise to chains. Furthermore, there are Ag...O interactions with a separation of 2.765 (2) Å between chains. The F atoms of the CF3CO2− anion are disordered over two sites with refined occupancies of 0.593 (5) and 0.407 (5).
