Crystal structure of dichloridobis(N,N′-dimethylthiourea-κS)mercury(II)

Abstract

The molecular structure of the title compound, [HgCl2(C3H8N2S)2], has point group symmetry 2, with the twofold rotation axis passing through the HgIIatom. The latter is coordinated by two Cl atoms and twoN,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)°. Intra- and intermolecular hydrogen bonds of the type N—H...Cl withS(6) andR22(12) ring motifs are present. The intermolecular contacts make up polymeric chains extending parallel to [101].
