Abstract

Spectroscopic studies show that [RhH(CO)(2)(PPr3i)(2)] exists as three different isomers. The two major isomers are rotamers, which have trigonal-bipyramidal geometry with axial H and two equatorial phosphines (ee) distorted toward square pyramidal in such a way that the hydride can migrate rapidly through the equatorial plane between the phosphines to equilibrate the two carbonyls, while the third isomer has an axial hydride and phosphines in both axial and equatorial positions (ea).
