| pubmed-article:12120406 | pubmed:abstractText | 1H and 19F Pulsed Gradient Spin Echo (PGSE) diffusion data, together with 1H, 19F-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. | lld:pubmed |
