Poly[[[μ(3)-(E)-N-(pyridin-4-yl­methyl­idene)hy­droxy­laminato-κ(3) O:N:N′][μ(2)-(E)-N-(pyridin-4-yl­methyl­idene)hydroxyl­amine-κ(2) N:N′][(E)-N-(pyridin-4-yl­methyl­idene-κN)hydroxyl­amine]­disilver(I)] nitrate]

The title coordination polymer, {[Ag(2)(C(6)H(5)N(2)O)(C(6)H(6)N(2)O)(2)]NO(3)}(n), features a deprotonated N-(pyridin-4-yl­methyl­idene)hy­droxy­laminate anion and two neutral N-(pyridin-4-yl­methyl­idene)hydroxyl­amine mol­ecules in the asymmetric unit. The anion connects three Ag(I) atoms through its O and two N-donor atoms. One neutral ligand functions in a monodentate mode; the other functions in a bridging mode, binding though its two N atoms. The coordination geometry of the two independent metal atoms is T-shaped; the manner of bridging gives rise to a layer motif parallel to (100). In the crystal, the nitrate ion is disordered over two positions in a 1:1 ratio, and is sandwiched between adjacent layers. O—H⋯O hydrogen bonding is present between nitrate ions and layers, and also between adjacent layers.
