title: Tetra-aqua-bis(2-oxo-1,2-dihydro-pyridine-5-sulfonato-κO)zinc(II).
abstract: The metal atom in the title compound, [Zn(C(5)H(4)NO(4)S)(2)(H(2)O)(4)], lies on a center of inversion and is linked to the anionic ligand through the carbonyl O atom. In the crystal structure, the 2-oxo-1,2-dihydro-pyridine-5-sulfon-ate ligand inter-acts with other mol-ecules through N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network structure.
