Crystal structure and Hirshfeld surface analysis of bis­[(eth­oxy­methane­thio­yl)sulfanido](N,N,N′,N′-tetra­methyl­ethane-1,2-di­amine)­mercury(II)

The title four-coordinate mononuclear complex, [Hg(C(3)H(5)OS(2))(2)(C(6)H(16)N(2))] or [Hg(C(3)H(5)OS(2))(2)(tmeda)] (tmeda: N,N,N′,N′-tetra­methyl­ethane-1,2-di­amine), has a distorted tetra­hedral geometry. The Hg(II) ion is coordinated to two N atoms of the N,N,N′,N′-tetra­methyl­ethylenedi­amine ligand and two S atoms from two ethylxanthate xanthate ligands. In the crystal, mol­ecules are linked by weak C—H⋯S hydrogen bonds, forming a two-dimensional supra­molecular architecture in the ab plane. The most important contributions for the crystal packing are from H⋯H (59.3%), S⋯H (27.4%) and O⋯H (7.5%) inter­actions.
