catena-Poly[[aquanickel(II)]-di-μ-(4-pyridylsulfanyl)acetato-κ6N:O,O;O,O':N]

The water-coordinated Ni atom in the title compound, [Ni(C7H6NO2S)(2)(H2O)](n), is covalently bonded to two carboxylate groups ( one binding in a monodentate mode and the other in a chelating mode); it is also linked to the N atoms of two other carboxylate anions in an octahedral environment. The compound adopts a linear chain architecture; adjacent chains are linked into layers by hydrogen bonds
