catena-Poly[[[[N′-(4-cyano­benzyl­idene)nicotinohydrazide]silver(I)]-μ-[N′-4-cyano­benzyl­idene)nicotinohydrazide]] hexa­fluoridoarsenate]

In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]AsF(6)}(n), the Ag(I) 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—N(carbonitrile) bond distance is significant longer than those of Ag—N(pyrid­yl). The bond angles around the Ag(I) atom are also not in line with those in an ideal T-shaped geometry. One type of ligand acts as the bridge that connects Ag(I) atoms into chains along [[Image: see text]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 [AsF(6)](−) counter-anions are linked to the hydrazone groups through N—H⋯F hydrogen bonds. Four of the F atoms of the [AsF(6)](−) anion are disordered over two sets of sites with occupancies of 0.732 (9) and 0.268 (9).
