Crystal Structure and Hirshfeld Surface Analysis of Bis[(ethoxymethanethioyl)sulfanido](N,N,N′,N′-Tetramethylethane

Abstract

The title four-coordinate mononuclear complex, [Hg(C3H5OS2)(2)(C6H16N2)] or [Hg(C3H5OS2)(2)(tmeda)] (tmeda: N,N,N',N'-tetramethylethane-1,2-diamine), has a distorted tetrahedral geometry. The HgII 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 center dot center dot center dot S hydrogen bonds, forming a two-dimensional supramolecular architecture in the ab plane. The most important contributions for the crystal packing are from H center dot center dot center dot H (59.3%), S center dot center dot center dot H (27.4%) and O center dot center dot center dot H (7.5%) interactions.
