Abstract: In the planar [r.m.s. deviation 0.0265 Å] title compound, [Hg(C₇H₅O₂)Cl], the Hg^II atom shows a typical linear coordination by a C atom of a benzene ring and a Cl atom. The benzene C atom and the aldehyde O atom chelate the Hg^II atom by assuming the HgO separation of 2.817 (9) Å as a weak intramolecular coordination bonding distance. The resulting five-membered metallacycle is nearly coplanar with the benzene ring dihedral angle 2.9 (1)°]. Intermolecular O-HO hydrogen bonds are present in the crystal structure, resulting in a one-dimensional supramolecular architecture parallel to [201].
