A host–guest complex of di­aqua­bis­[1‐hydroxy‐2(1H)‐pyridine­thionato‐O,S]­magnesium(II) and 2,2′‐di­thio­bis­(pyridine N‐oxide)

The title compound, Mg(C₅H₄NOS)₂(H₂O)₂]·C₁₀H₈N₂O₂S₂, is a two‐component host–guest material. The 2,2′‐di­thio­bis(pyridine N‐oxide) molecule has crystallographic twofold symmetry. The metal complex lies on an inversion centre and associates via C—H?S interactions into chains which thread the 2,2′‐di­thio­bis­(pyridine N‐oxide) lattice in perpendicular directions. Hydro­gen bonds exist between the water mol­ecules of the di­aqua­magnesium units and the N—O groups of the host lattice.
