Abstract: The title compound, [Hg₂(C₁₄H₁₃N₄S)₂I₂], is a dimeric complex of mercury(II) with the N,N,S-tridentate electron-donor Schiff base ligand and lies on a crystallographic twofold axis. The two Hg atoms are linked by two bridging S atoms, forming a rectangular base with Hg-S bond lengths of 2.6490  (12) and 2.6173  (11)  Å. The two tridentate ligands are almost perpendicular to the base, resulting in an open box-like structure. The geometry of the Hg atoms is between trigonal bipyramidal and square pyramidal, but closer to the latter.
