The organic sheets are interlinked through weak C—H...O hydrogen bonds, while they interact with the anionic part via strong charge-assisted N+—H...Cl—Hg hydrogen bonds. The [HgCl4]2 anions are bisected by a mirror plane passing through the metal and two of the chloride ions.enInternational Union of CrystallographyBis(2-methyl-4-nitroanilinium)CationsAnionsArticle
