Complexes having the empirical formulae M(DEBCTA) 2 X 2 (M = Zn or Cd, X = Br or I, DEBCTA = N,N‐diethylbenzenecarbothioamide), Zn(DEBCTA)Cl 2 , Cd 2 (DEBCTA)Cl 4 and Hg(DEBCTA)X 2 (X = Cl, Br or I) were made by reaction of zinc, cadmium or mercury dihalides in ethanol or 1,2‐dichloroethane. All complexes have been characterized by elemental analysis, conductance and molecular weight measurements and by infrared and 1 H‐NMR spectral studies. In addition, the structure of [Hg(DEBCTA)I 2 ] 2 has been determined by single‐crystal X‐ray crystallography and refined to a conventional R factor of 0.097. The compound crystallizes in the monoclinic space group P2 1 /n with a = 1383.9(2), b = 834.3(1), c = 1418.2(2) pm, β = 101.03(1)° and Z = 2. The molecule was found to have a dimeric structure involving two asymmetrical iodine bridges in which the Hg atom lies a tetrahedral environment and the ligands lie mutually trans with respect to one another.
