abstract: The title coordination polymer, {[Ag2(C6H5N2O)(C6H6N2O)2]NO3} n , features a deprotonated N-(pyridin-4-yl-methyl-idene)hy-droxy-laminate anion and two neutral N-(pyridin-4-yl-methyl-idene)hydroxyl-amine mol-ecules 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.
