title: Tetra-aqua-bis-[2-(4-pyridyl-sulfan-yl)acetato-κN]nickel(II).
abstract: In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], the Ni(II) atom, located on a centre of inversion, is coordinated by two N atoms from two 2-(4-pyridyl-sulfan-yl)acetate ligands and four water O atoms in an octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate group of the anionic 2-(4-pyridyl-sulfan-yl)acetate ligands link these discrete mononuclear units into a three-dimensional network.
