Bis[N-(4-nitro­phen­yl)thio­benz­amidato]­mercury(II)

The mol­ecule of the title compound, [Hg(C₁₃H₉N₂O₂S)₂], has approximate twofold rotation symmetry, with the Hg atom in an essentially linear two-coordinate HgS₂ environment supported by secondary π inter­actions with the nitro­phenyl rings of both ligands. The ligands are in the imine–thiol­ate rather than the amine–thione tautomeric form.
