title: catena-Poly[[bis-(μ(2)-4-amino-benzene-sulfonato-κO:O)disilver]-bis-(μ(2)-4,4'-bipyridine-κN:N')].
abstract: In the title compound, [Ag(2)(C(6)H(6)NO(3)S)(2)(C(10)H(8)N(2))(2)](n), the Ag(I) atom is four-coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) and two O atoms from two independent 4-amino-benzene-sulfonate (ABS) ligands. The two inter-chain Ag(I) atoms are bridged by two independent ABS ligands through weak Ag-O bonds and Ag⋯Ag attractions, forming a ladder-like chain coordination polymer [Ag(2)(ABS)(2)(bipy)(2)](n) parallel to [001], which is further linked to generate a two-dimensional structure via N-H⋯O hydrogen-bonding inter-actions.
