Relationship of hydride fluxionality in Ir(H)(2)L(phosphine)(2)(n+) to properties of L : An exceptional range of barrier heights
The site exchange process illustrated here shows Delta H double dagger values from 4.8 to 11.6 kcal/mol, depending on the identity of L (halide, OSO2CF3, HN3, CO, H-2, NHC(O)CH3, (PPr2Ph)-Pr-i, PCy2Ph).
