Abstract: In the title compound, [HgCl₂(C₁₂H₆N₂O₂)₂], the Hg^II atom is located on a twofold rotation axis and exists within a distorted octahedral geometry defined by a cis-Cl₂N₄ donor set. Molecules are connected into layers in the ac plane via extensive C-HCl contacts as each Cl atom forms two such interactions. Contacts between the layers are of the type C=O [Ocentroid distance = 3.110 (8) Å].
