N2 - A variable-temperature proton NMR study of the dimer-monomer equilibrium in the [CpCr(CO)2L]2 complexes [(1), L = CO; (2), L = P(OMe)3] and application of van't Hoff's equation gave the following thermodynamic parameters: 1, ΔH = 21.3±0.7 kcal mol-1, ΔS = 50.7±2.2 cal mol-1 K-1 and ΔG300 = 6.1 kcal mol-1; 2, ΔH = 18.8±0.4 kcal mol-1, ΔS = 69.0±1.5 cal mol-1 K-1 and ΔG300 = -1.9 kcal mol-1.
