Iodido{4-phenyl-1-[1-(1,3-thia-zol-2-yl-κN)ethyl-idene]thio-semicarbazidato-κN',S}{4-phenyl-1-[1-(1,3-thia-zol-2-yl)ethyl-idene]thio-semicarbazide-κS}mercury(II).

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 1.685 (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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
