Zusammenfassung:Previously reported (J. Organomet. Chem., 246 (1983) 309) experimental data for the equilibrium constants and thermodynamic parameters of the reversible reaction 2 Rh 2(CO) 8 ⇄ Rh 4(CO) 12 + 4 CO have been re-evaluated using more reliable values for the solubility of carbon monoxide in hexane at lower than room temperature and introducing also a fugacity vs. pressure correction for carbon monoxide. The new values are: Δ H0 = 58.6 ± 10 kJ mol −1 and Δ S 0 = 305 ± 25 J mol −1 K −1
