Abstract
In the title compound, {[Ag(C14H10N4O)2]AsF6}n, the AgI ion is coordinated by two N atoms from two different pyridyl rings and one N atom from one carbonitrile group of three different N′-(4-cyanobenzylidene)nicotinohydrazide ligands in a distorted T-shaped geometry. The Ag—Ncarbonitrile bond distance is significant longer than those of Ag—Npyridyl. The bond angles around the AgI atom are also not in line with those in an ideal T-shaped geometry. One type of ligand acts as the bridge that connects AgI atoms into chains along [01]. These chains are linked to each other via N—H⋯O hydrogen bonds and Ag⋯O interactions with an Ag⋯O separation of 2.869 (2) Å. In addition, the [AsF6]− counter-anions are linked to the hydrazone groups through N—H⋯F hydrogen bonds. Four of the F atoms of the [AsF6]− anion are disordered over two sets of sites with occupancies of 0.732 (9) and 0.268 (9).
