|Title:||Zinc-sulphur Bond Enthalpy: Its Determination In The Compound Bis(diethyldithiocarbamato)zinc(ii)|
|Abstract:||The standard enthalpy of formation of bis(diethyldithiocarbamato)zinc(II), as well as that of the salt diethylammonium chloride, has been determined by solution calorimetry at 298.15 K, giving -(289.65 ± 4.9) and -(359.63 ± 1.22) kJ mol-1, respectively. From the standard enthalpy of formation of the chelare, the enthalpy of formation in the gaseous phase, ΔHf⊖[Zn(S2CNEt2) 2,g] = -(147.0 ± 5.0) kJ mol-1 was derived. The homolytic and heterolytic zinc-sulphur bond enthalpy parameters were calculated to be 177.4 ± 3.5 and 740.2 ± 3.5 kJ mol-1, respectively. These values are discussed and appear to correlate with the zinc-sulphur bond distance. © Copyright 1985 by the Royal Society of Chemistry.|
