Abstract
The paper reports variations in LIS for [Yb(H2O)n(EDTA)]− and [Yb2(EDTA)3]6− complexes as a result of variation in pD and temperature. This is the first detection of kinetically stable complexes of the yttrium subgroup with stoichiometric ratio of 2:3. The experimental paramagnetic lanthanide-induced chemical shift values of these compounds are well fitted by linear dependence on 1/T at different pH values. The [Yb(H2O)n(EDTA)]− complex can be considered as one of the most promising combined NMR spectroscopic probe to determine temperature and pH in aqueous media.
