Poly[[[mu(3)-(E)-N-(pyridin-4-ylmethylidene)hydroxylaminato-kappa O-3:N: N'][mu(2)-(E)-N( pyridin-4-ylmethylidene) hydroxylaminej 2 N: N'][(E)-N-(pyridin-4-ylmethylidenejN) hydroxylamine] disilver(I)] nitrate]

The title coordination polymer, {[ Ag-2(C6H(5)N(2)O)(C6H6N2O)(2)] NO3}(n), features a deprotonated N-(pyridin-4-ylmethylidene) hydroxylaminate anion and two neutral N-(pyridin-4ylmethylidene) 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 center dot center dot center dot O hydrogen bonding is present between nitrate ions and layers, and also between adjacent layers.
