Reaction of Non-Symmetric Schiff Base Metallo-Ligand Complexes Possessing an Oxime Function with Ln Ions

Autor: Jean-Pierre Costes, Françoise Dahan, Arnaud Dupuis, Sergiu Shova, Javier Garcia Tojal

Publikováno v: Inorganics, Vol 6, Iss 1, p 33 (2018)

The preparation of non-symmetric Schiff base ligands possessing one oxime function that is associated to a second function such as pyrrole or phenol function is first described. These ligands, which possess inner N4 or N3O coordination sites, allow f
