title: catena-Poly[[diaquacadmium(II)]bis-(μ-pyridine-3-sulfonato)-κN:O;κO:N].
abstract: In the title polymeric complex, [Cd(C(5)H(4)NO(3)S)(2)(H(2)O)(2)](n), the Cd atom is located on a centre of inversion and is coordinated by two O atoms and two N atoms, derived from four different pyridine-3-sulfonate ligands, and two O atoms derived from two water mol-ecules, forming a distorted trans-N(2)O(4) octa-hedral geometry. The topology of the polymer is a one-dimensional chain mediated by bridging pyridine-3-sulfonate anions. These are connected into a three-dimensional architecture via hydrogen bonds.
