Tetra­aqua­bis­[4-(pyrazin-2-ylsulfanylmethyl-κN (4))benzoato]cobalt(II)

In the title compound, [Co(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)], the Co(II) ion, lying on an inversion center, has an octa­hedral coordination involving two N atoms of two 4-(pyrazin-2-ylsulf­anylmeth­yl)benzoate ligands and four water mol­ecules. In the crystal, O—H⋯O hydrogen bonds between the coordinated water mol­ecules and uncoordinated carboxyl­ate O atoms, and weak π–π inter­actions [centroid–centroid distance = 4.105 (2) Å] between the benzene and pyrazine rings lead to a three-dimensional supra­molecular network.
