Bis[2-(2-pyridylmethyl-eneamino)benzene-sulfonato-κN,N',O]zinc(II) dihydrate.

In the title complex, [Zn(C(12)H(9)N(2)O(3)S)(2)]·2H(2)O, the Zn(II) ion lies on a crystallographic inversion center and is coordinated by four N atoms and two O atoms from two tridentate 2-(2-pyridylmethyl-eneamino)benzene-sulfonate ligands in a slightly distorted octa-hedral environment. In the crystal structure, the complex forms a two-dimensional network through inter-molecular O-H⋯O and C-H⋯O hydrogen bonds.
