title: catena-Poly[[silver(I)-μ-N-(3-pyridyl-meth-yl)pyridine-4-carboxamide] nitrate monohydrate].
abstract: In the title compound, {[Ag(C(12)H(11)N(3)O)]NO(3)·H(2)O}(n), the Ag atom is coordinated by two N atoms from the heterocyclic ligand, giving a linear polycationic chain. Two long Ag⋯O(nitrate) inter-actions [2.667 (3) and 2.840 (3) Å] result in a three-dimensional network. The water mol-ecule consolidates the network structure by forming hydrogen bonds, one to the polycationic chain and one to the nitrate anion.
