Abstract

For the first time we study the stability of the lanthanide complexes with polydentate hyterocyclic phosphine oxides. Here we report the influence of the structure of phenanthroline (PhenPPO) and 2,2’-bipyridine (DPPO) phosphine oxides on the stability of their lanthanide complexes. An increase in the flexibility of the phosphine oxide structure leads to an increase in the stability of the complexes. The maximum of stability of the complexes is observed on neodymium ion, regardless of the structure of the ligands DPPO and PhenPPO.
