The standard molar enthalpies of formation of crystalline dialkyldithiocarbamates chelates, [Pd(S2CNR2)(2)], with R=C2H5, n-C3H7, n-C4H9 and i-C4H9, were determined through reaction-solution calorimetry in acetone, at 298.15 K. From the standard molar enthalpies of formation of the gaseous chelates, the homolytic (172.4+/-3.8, 182.5+/-3.2, 150.9+/-3.1 and 162.6+/-3.1 kJ mol(-1)) and heterolytic (745.0+/-3.8, 803.7+/-3.3, 834.3+/-3.1 and 735.2+/-3.0 kJ mol(-1)) mean palladium-sulphur bond-dissociation enthalpies were calculated.
