Oligonuclear Metal Complexes with Schiff Base Ligands.

This review thoroughly covers aspects of synthetic chemistry, reactivity, and the properties of dinuclear and oligonuclear actinoid complexes based on Schiff base ligands within the last 20 years in an extensive way and with clear presentation. 10.3390/molecules181012264 6 Liu X., Hamon J.-R. Recent Developments in Penta-, Hexa- and Heptadentate Schiff Base Ligands and Their Metal Complexes. As stated by two of the seven papers [[1]] published in the Special Issue entitled "Oligonuclear Metal Complexes with Schiff Base Ligands" that I guest edited, the chemistry of Schiff bases began in 1864 due to the discovery made by Hugo Schiff [[3]], but even more than one and a half centuries after their first synthesis, Schiff bases continue to surprise inorganic chemists. C=N is usually incorporated into more articulated architectures in addition to other donor atoms, the so-called polydentate ligands [[6]], since metal complexes with macrocyclic and acyclic polydentate Schiff bases [[7]] show enhanced thermodynamic stability due to the chelating effect [[9]].
