| Abstract: | ![]()
The standard molar enthalpy of formation of crystalline di-isobutyldithiocarbamate complexes of P, As, Sb and Bi(III) has been derived by solution calorimetry at 298.15 K. The corresponding standard molar enthalpies of sublimation were estimated by means of differential scanning calorimetry. From the standard molar enthalpies of formation of the gaseous chelates the homolytic and heterolytic mean metal-sulphur bond-dissociation enthalpies were calculated.We thank to CNPq and to PADCT for financial support of this work and also to Dr. Claudio Airoldi (UNICAMP) by facility offered for obtaining of the solution-reaction calorimetric measurements. |
