摘要：

H-1 and F-19 Pulsed Gradient Spin Echo (PGSE) diffusion data, together with H-1, F-19-HOESY results are shown to distinguish between different types of anion/cation interactions in chiral dihydrido-P, N-complexes of Ir(III); in CD2Cl2 the diffusion coefficients, D, for the BArF and the Ir-cation suggest ion-pairing whereas the D-values for PF6- reveal independent motion; the PF6- approaches the cation via a specific pathway; the combined PGSE/HOESY approach offers a unique opportunity for exploring anion effects in organometallic/catalytic chemistry.
