The structure of the title compound, poly[[[mu(3)-N'-(3-cyanobenzylidene)nicotinohydrazide]silver(I)] hexafluoroarsenate], {[Ag(C14H10N4O)](AsF6)}(n), at 173 K exhibits a novel stair-like two-dimensional layer and a three-dimensional supra-molecular framework through C-H center dot center dot center dot Ag hydrogen bonds. The Ag-I cation is coordinated by three N atoms and one O atom from N'-(3-cyanobenzylidene)nicotinohydrazide (L) ligands, resulting in a distorted tetrahedral coordination geometry. The organic ligand acts as a mu(3)-bridging ligand through the pyridyl and carbonitrile N atoms and deviates from planarity in order to adapt to the coordination geometry. Two ligands bridge two Ag-I cations to construct a small 2 2 Ag2L2 ring. Four ligands bridge one Ag-I cation from each of four of these small rings to form a large grid. An interesting stair-like two-dimensional (3,6)-net is formed through Ag-I metal centres acting as three-connection nodes and through L molecules as tri-linkage spacers.
