摘要：

We describe the synthesis and characterization by elemental analysis, conductance measurements and H-1 NMR and IR spectrometry of compounds with the general formula [M(BBDH)X2] [M = Zn, Cd or Hg; X = Cl, Br or I; BBDH = 1,6-bis(benzimidazol-2-yl)-2,5-dithiahexane], which were prepared by reaction of zinc, cadmium or mercury dihalides with BBDH in ethyl alcohol. In addition, the structure of Hg(BBDH)Cl2.EtOH (VI) was determined by single-crystal structure analysis. The mercury atom is coordinated with slightly distorted tetrahedral geometry to the unprotonated nitrogen atoms of the BBDH benzimidazolyl groups [Hg-N = 225.8(5) and 223.6(6) pm] and to two chlorine atoms [Hg-Cl = 251.3(3) ana 249.9(2) pm].
