摘要

Two mercury(II) complexes of 4,5-ethylenedithio-1,3-dithiole-2-thione (C5H4S5), [Hg-2(C5H4S5)(2)Cl-4] (1) and [Hg-2(C5H4S5)(2)Br-4] (2), were synthesized and the structure of complex 1 was characterized crystallographically. Complex 1 has a dimeric structure, in which each mercury atom takes a tetrahedral geometry and is coordinated by two bridging chloride, one terminal chloride and one thiocarbonyl sulfur atom (C=S) of the ligand. These dimers are further packed to form a one dimensional ribbon structure via intermolecular S ... S and S ... Cl contacts. All of the ligands in the ribbon are co-planar and weakly conjugated.
