- Diiodine adducts with cyclic dithio‐oxamides, where complexing and oxidising properties coexist in the same molecule, have been shown to be powerful oxidising reagents towards selected metals. Here we describe the reaction of Me2dazdt·2I2 [Me2dazdt = 1,4‐dimethylperhydro‐1,4‐diazepine‐2,3‐dithione (1)] with highly toxic liquid mercury which gives the complex [Hg(Me2dazdt)I2] (2) in a one‐step reaction. X‐rays analysis of 2 shows that the HgII centre is coordinated by two sulfur atoms of the chelating ligand and by two iodine atoms in a distorted tetrahedral geometry. The molecule is asymmetric and crystallizes in the chiral space group P212121. In the unit cell only the M enantiomer is present [τ (S1−C1−C2−S2) = −61.1(5)°]. (© Wiley‐VCH Verlag GmbH & Co.
