Abstract

Abstract The standard enthalpies of formation of alkaline metals thiolates in the crystalline state were determined by reaction-solution calorimetry. The obtained results at 298.15 K were as follows: f H_ m^ o (MSR, cr)/kJ mol− 1=− 259.0±1.6 (LiSC 2 H 5),− 199.9±1.8 (NaSC 2 H 5),− 254.9±2.4 (NaSC 4 H 9),− 240.6±1.9 (KSC 2 H 5),− 235.8±2.0 (CsSC 2 H 5). These results where compared with the literature values for the corresponding alkoxides and ...
