Catena-Poly[[[[N'-(4-cyano-benzyl-idene)nicotinohydrazide]silver(I)]-μ-[N'-4-cyano-benzyl-idene)nicotinohydrazide]] hexa-fluoridoarsenate].

ABSTRACT: 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-cyano-benzyl-idene)nicotinohydrazide ligands in a distorted T-shaped geometry. The Ag-N(carbonitrile) bond distance is significant longer than those of Ag-N(pyrid-yl). 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 [01]. These chains are linked to each other via N-H⋯O hydrogen bonds and Ag⋯O inter-actions 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. Fou
