Реферат:
Lanthanide complexes from La to Yb with [PW11O39]7- ligands were studied by 17O, 31P and 183W NMR methods. The complexes are non-labile on the NMR time scale, and their 1: 2 composition in solution was confirmed by 31P NMR. Contact and dipolar contributions to the lanthanide induced shift (LIS) of ligand nuclei have been estimated. The geometry of the ligand was shown to change in the lanthanide series and the dipolar contribution to LIS increases compared to the contact contribution, as the distance from the lanthanide ion increases.
