摘要：

Entropies for several gas-phase ML4 and ML6 neutral and ionic transition-metal complexes are estimated from structural and spectroscopic data. It is demonstrated that vibrational entropies provide a substantial portion (up to 42% in the cases analyzed here) of the total entropy for such complexes as a result of low-frequency skeletal modes. The contributions of vibrational and electronic entropy changes to reaction entropies for a number of related redox couples are also estimated.
