catena-Poly[[bis(mu2-4-methylbenzoato-kappa2O:O')disilver(I)(Ag-Ag)]-mu2-di-2-pyridylamine-kappa2N2:N2'] and catena-poly[[(di-2-pyridylamine-kappaN2)(mu2-4-nitrobenzoato-kappa2O:O')disilver(I)(Ag-Ag)]-mu3-4-nitrobenzoato-kappa3O:O':O'].

Both title compounds are polynuclear polymeric complexes with binuclear units. In the former compound, [Ag2(C8H7O2)2(C10H9N3)]n, the two Ag(I) atoms display distorted square-planar coordinations. This compound contains a twofold axis and a crystallographic inversion centre, and di-2-pyridylamine (DPA) ligands crosslink adjacent binuclear units to form infinite polymeric chains.
