In the title compound {alternative name: poly[silver(I)-mu-(3-amino-2-chloropyridine)-mu-nitrato]}, [Ag(NO3)(C5H5ClN2)](n) the Ag-I atom is in an irregular AgN2O3 geometry, surrounded by one pyridyl N atom [Ag-N 2.283 (5) Angstrom], one amine N atom [Ag-N 2.364 (6) Angstrom] and three O atoms from different nitrate ions [Ag-O 2.510 (6)-2.707 (6) Angstrom]. The Ag ions are bridged by the 3-amino-2-chloropyridine ligands into helical chains. Adjacent uniform chiral chains are further interlinked through the NO3 bridges into an interesting two-dimensional coordination network in the solid.
