Supplement 7. Mechanism for Interchanging Apical and Equatorial Atoms in IBr5 via a C2v Transition State

A: Calculated Ground State Structure for IBr5
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/pVTZ)
