ABSTRACT
In the title compound, [Hg(C(12)H(11)N(4)S(2))I(C(12)H(12)N(4)S(2))], the Hg atom is in a distorted square-pyramidal coordination, defined by the iodide ligand, by the S atom of the neutral ligand in the apical position, and by the N atom of the thia-zole ring, the thio-ureido N and the S atom of the deprotonated ligand. The deprotonated ligand intra-molecularly hydrogen bonds to the thia-zole ring N atom, while the deprotonated ligand forms an inter-molecular hydrogen bond to the thiol-ate 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 distance is 1.685â
(7)â
Å, whereas it is 1.749â
(7)â
Å in the deprotonated ligand. Similarly, the Hg-S bond distance is slightly longer to the neutral ligand [2.6682â
(18)â
Å] than to the deprotonated ligand [2.5202â
(19)â
Å]. The Hg-I distance is 2.7505â
(8)â
Å.
