Slow epimerization of stereochemically rigid diastereomers of the equatorially substituted cluster [Os3H2(mu 3-S)(CO)8((S)-PhCHMeNH2)].
Turnstile rotation is suppressed in the equatorially substituted cluster [Os3(mu-H)2(mu 3-S)(CO)8((S)-PhCHMeNH2)] which was separated by HPLC into two diastereomers which do not interconvert at room temperature and epimerize only slowly at 90 degrees C.
