Abstract
The molecular 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'-dimethylthiourea (Dmtu) ligands through their S atoms, defining a distorted tetrahedral coordination sphere with bond angles in the range 102.47 (4)-118.32 (4)degrees. Intraand intermolecular hydrogen bonds of the type N-H center dot center dot center dot Cl with S(6) and R-2(2) (12) ring motifs are present. The intermolecular contacts make up polymeric chains extending parallel to [101].
