title: Diaqua-bis-(pyridine-2-sulfonato-κN,O)cobalt(II).
abstract: The title complex, [Co(C(5)H(4)NO(3)S)(2)(H(2)O)(2)], lies on a twofold rotation axis that relates the two water mol-ecules and the two pyridine-2-sulfonate ions. The Co(II) atom exists in an slightly distorted octa-hedral environment. The N-donor atoms are cis to each other. In the crystal, adjacent mol-ecules are linked by O-H⋯O hydrogen bonds into a layer motif extending along (001).
