Resumen
The standard enthalpy change (ΔHR ⊖) for the reaction MCl2(s) + nDMA(I) → [MCl2(DMA)n] (s) (M = Zn, n = 2; M = Cd or Hg, n = 1; DMA = NN-dimethylacetamide) as measured by solution calorimetry gave values -84.2 ± 1.6 (Zn), -29.2 ± 0.2 (Cd), and 25.2 ± 0.7 (Hg) kJ mol-1, respectively. The values of the standard enthalpy of formation (ΔHf ⊖) of the adducts were determined from values of ΔHR ⊖, and the standard enthalpies of formation of NN-dimethylacetamide and the metal chlorides, giving the values -1 055 ± 5, -698 ± 2, and -527 ± 2 kJ mol-1 for zinc, cadmium, and mercury, respectively.
