Crystal structure of di-chlorido-bis-(N,N'-di-methyl-thio-urea-κS)mercury(II).

The mol-ecular structure of the title compound, [HgCl2(C3H8N2S)2], has point group symmetry 2, with the twofold rotation axis passing through the Hg(II) atom. The latter is coordinated by two Cl atoms and two N,N'-di-methyl-thio-urea (Dmtu) ligands through their S atoms, defining a distorted tetra-hedral coordination sphere with bond angles in the range 102.47 (4)-118.

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

In the title compound, [HgCl(2)(C(5)H(12)N(2)S)(2)], the Hg(II) atom is located on a twofold rotation axis and is bonded in a distorted tetra-hedral coordination mode to two chloride ions and to two tetra-methyl-thio-urea (tmtu) mol-ecules through their S atoms. The crystal structure is stabilized by C-H⋯N and C-H⋯S hydrogen bonds.

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.

Bis(1,3-dibutylthiourea)dicyanido-mercury(II).

In the title compound, [Hg(CN)(2)(C(9)H(20)N(2)S)(2)], the Hg atom lies on a twofold rotation axis. There is only half a mol-ecule in the asymmetric unit. The Hg atom has a distorted tetra-hedral coordination involving the S atoms of two 1-butyl-3-propyl-thio-urea groups and the C atoms of the two CN(-) anions.
