In the asymmetric unit of the title compound, [HgCl2(C16H14N4S)], the HgIIcation is linked to two Cl atoms and two imidazole N atoms of the chelating bis[(1H-benzimidazol-2-yl)methyl]sulfane ligand, forming a slightly distorted tetrahedral environment. The substitued imidazole rings of the ligand are almost perfectly planar [with maximum deviations of 0.017 (3) and 0.012 (3) Å] and form a dihedral angle of 42.51 (5)°. The crystal packing can be described as alternating layers parallel to (010). In this arrangement, N—H...Cl hydrogen bonds between the N—H groups of the benzimidazole moieties and chloride ligands are responsible for the formation of the chain-like packing pattern along [010] exhibiting aC(6) graph-set motif.
