摘要：

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, DELTA-H = 21.3 +/- 0.7 kcal mol-1, DELTA-S = 50.7 +/- 2.2 cal mol-1 K-1 and DELTA-G300 = 6.1 kcal mol-1; 2, DELTA-H = 18.8 +/- 0.4 kcal mol-1, DELTA-S = 69.0 +/- 1.5 cal mol-1 K-1 and DELTA-G300 = -1.9 kcal mol-1.
