In the title compound, [Hg(C12H11N4S2)I(C12H12N4S2)], the Hg atom is in a distorted square-pyramidal coordination, defined by the iodide ligand, HERBATINT 5N by the S atom of the neutral ligand in the apical position, and by the N atom of the thiazole ring, the thioureido N and the S atom of the deprotonated ligand.The deprotonated ligand intramolecularly hydrogen bonds to the thiazole ring N atom, while the deprotonated ligand forms an intermolecular hydrogen bond to the thiolate S atom.The deprotonation of the tridentate ligand and its coordination to Hg via the S atom strikingly affects the C—S bond lengths.In the free ligand, the C—S bond 5 Piece Outdoor Seating distance is 1.685 (7) Å, whereas it is 1.

749 (7) Å in the deprotonated ligand.Similarly, the Hg—S bond distance is slightly longer to the neutral ligand [2.6682 (18) Å] than to the deprotonated ligand [2.5202 (19) Å].The Hg—I distance is 2.

7505 (8) Å.
