title: Crystal structure of di-chlorido-bis-(N,N'-di-methyl-thio-urea-κS)mercury(II).
abstract: 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)-118.32 (4)°. Intra- and inter-molecular hydrogen bonds of the type N-H⋯Cl with S(6) and R 2 (2)(12) ring motifs are present. The inter-molecular contacts make up polymeric chains extending parallel to [101].
