La-NMR studies on Cp3Ln L, where L = DMSO, DMF, OP(OMe)3 and OCMe2 have been reported [39]. Magnetic susceptibility data and EPR spectra of Cp3 Yb L, L =... 

Anions which may be termed as innocent from the point of coordination readily coordinate in organic solvents like methanol and acetonitrile [28-30], Using 139La NMR,... 

The 139La NMR has been used for obtaining relaxation rates at different frequencies and hence correlation times which have been applied to La3+-bovine serum albumin [43],... 

Analysis of the entropy changes, indicates essentially 100% inner sphere formation for the Ac, 3 ClPr and ClAc complexes, 50% inner sphere for the CI2AC complexes. However, a study of 139La nmr shifts (18) was interpreted to show only 50% inner sphere character for LaClAc+2 and 20-25% for LaCl2Ac+. In light of this lack of agreement, we have analysed the complexation by another approach which would seem to be more justified than the entropy based estimations.
