title: Poly[(μ(6)-6-oxidopyridinium-2-carboxyl-ato)caesium].
abstract: The asymmetric unit of the polymeric title salt, [Cs(C(6)H(4)NO(3))](n), comprises a Cs(+) cation and a 6-oxidopyridinium-2-carboxyl-ate anion. The Cs(+) cation is six-coordinated by O atoms derived from two oxido and four carboxyl-ate O atoms; each O atom in the anion bridges two Cs(+) cations. In the crystal, inter-molecular N-H⋯O hydrogen bonding is present and contributes to the stability of the three-dimensional network generated by the bridging O atoms.
