Crystal structure of {bis-[(1H-benzimid-azol-2-yl-?N (3))meth-yl]sulfane}dichloridomercury(II).

ABSTRACT: 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.
