Supplement 5a. Mechanism for Interchanging Apical and Equatorial Atoms IF5 via a Cs Transition State

A: Calculated Ground State Structure for IF5
Viewing tools:


Impose a red/orange/blue color scheme to follow the atoms undergoing exchange:
Begin and stay equatorial red
Begin equatorial and become apical orange
Begin apical and become equatorial blue
Calculated Transition State B3LYP/cc-pV5Z-pp
