A. Baglia, Katharine A. Prokop-Prigge, Heather M. Neu, Maxime A. Siegler, David P. GoldbergIsomorphous
crystals of MnV(O) and CrV(O)
corrolazines were characterized by single crystal X-ray diffraction.
Reactivity studies with H atom donors and separated PCET reagents
show a dramatic difference in H atom abstracting abilities for these
two complexes. The implied large difference in driving force is opposite
the trend in redox potentials, indicating that basicity is a key factor
in determining the striking difference in reactivity for two metal-oxo
species in identical ligand environments.
