Dichloridobis(N,N'-diethyl-thio-urea-κS)mercury(II).

There are two mol-ecules in the asymmetric unit of the title compound, [HgCl(2)(C(5)H(12)N(2)S)(2)]. In both mol-ecules, the N,N'-diethyl-thio-urea ligands exhibit a cis,trans geometry around their C-N amide bonds. The shapes of the mol-ecules are, to a large extent, determined by intra-molecular N-H⋯Cl hydrogen bonds formed by the N-H groups from the cis amide groups. In one mol-ecule, these groups are involved in three-center hydrogen bonds involving both chloride ligands, whereas in the other mol-ecule only one Cl ligand takes part in intra-molecular hydrogen bonding. The coordination around the Hg atom is distorted tetra-hedral with an S(2)Cl(2) donor set. Inter-molecular hydrogen bonds between N-H groups from the trans amide units of the thio-amide ligands and the chloride ligands connect the mol-ecules into a polymeric chain extending along the c axis. One of the ethyl groups of the N,N'-diethyl-thio-urea ligands is disordered over two positions in one of the mol-ecules, with an occupancy of 0.654 (17) for the major component.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
