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