Abstract

The inner-sphere coordination of nitrate ions to lanthanide ions, in particular erbium, has been explored from studies of the density and molar absorptivity of erbium nitrate solutions and the chemical shift of 17O-enriched water in the presence of erbium and lithium nitrates. The dehydration of the erbium ion and replacement of water by nitrate in the inner coordination sphere are deduced from the data. The average ligand number in the inner sphere is lower than the total ligand number, so that some outer-sphere coordination also occurs, for all the lanthanides in nitrate solutions.
