title: catena-Poly[[bis-[(2-carboxy-benzoato-κO)silver(I)](Ag-Ag)]bis-(μ-isonicotinic acid-κN:O)].
abstract: The title compound, [Ag(C(8)H(5)O(4))(C(6)H(5)NO(2))](n), contains one Ag(I) atom, one phthalate ligand and one isonicotinic acid mol-ecule in the asymmetric unit. Each Ag atom is three-coordinated in a T-shaped geometry by two O atoms and one N atom from one phthalate ligand and two isonicotinic acid ligands. The isonicotinic acid ligand bridges two Ag atoms, forming a one-dimensional chain. Adjacent chains are linked by Ag-Ag inter-actions, leading to a double-chain. These double-chains are further linked via hydrogen bonds into a two-dimensional layer.
