In the asymmetric unit of the title compound, [HgCl2(C16H14N4S)], the Hg(II) cation is linked to two Cl atoms and two imidazole N atoms of the chelating bis-[(1H-benzimidazol-2-yl)meth-yl]sulfane ligand, forming a slightly distorted tetra-hedral environment. The substitued imidazole rings of the ligand are almost perfectly planar [with maximum deviations of 0.017 (3) and 0.012 (3) Å] and form a dihedral angle of 42.51 (5)°. The crystal packing can be described as alternating layers parallel to (010). In this arrangement, N-H⋯Cl hydrogen bonds between the N-H groups of the benzimidazole moieties and chloride ligands are responsible for the formation of the chain-like packing pattern along [010] exhibiting a C(6) graph-set motif.
在标题化合物[HgCl₂(C₁₆H₁₄N₄S)]的不对称单元中，Hg(II)阳离子与两个Cl原子以及螯合双-[(1H-苯并咪唑-2-基)甲基]硫烷配体的两个咪唑N原子相连，形成略微扭曲的四面体环境。配体的取代咪唑环几乎完全平面化[最大偏差为0.017 (3) 和0.012 (3) Å]，并形成42.51 (5)°的二面角。晶体堆积可描述为平行于(010)的交替层。在这种排列中，苯并咪唑部分的N-H基团与氯化物配体之间的N-H⋯Cl氢键导致沿[010]形成链状堆积模式，呈现C(6)图集 motif。
