Tetraaquabis[2-(4-pyridyl)ethanesulfonato-N]zinc(II).

The title compound, [Zn(C(7)H(8)NO(3)S)(2)(H(2)O)(4)], has an octahedral coordination around the central Zn atom composed of two axial N atoms from the pyridine ligands and four equatorial O atoms of water molecules, forming a monomeric centrosymmetric complex. The two Zn-N bond distances are 2.102 (3) A, while the four Zn-O bond distances range from 2.114 (2) to 2.167 (2) A. Packing is determined by hydrogen bonds formed by the water molecules. The sulfonate group does not take part in coordination to the Zn atom.
