Line Shape Analysis of Dynamic NMR Spectra for Characterizing Coordination Sphere Rearrangements at a Chiral Rhenium Polyhydride Complex

Line shape analysis of NMR spectra collected over a range of temperatures serves as a guide for the rearrangement of inner coordination-sphere atoms at a chiral, eight-coordinate, rhenium(V) polyhydride complex, ReH₅(PPh₃)₂(sec-butyl amine). Line shape analysis is also used to determine the activation parameters ΔH^‡, ΔS^‡, and ΔG^‡ for those atom rearrangements.
