Molecular structures of M(II) chelates with compartmental (N,N)-, (N,O)- and (N,S)-donor ligands and articulated metal chelate cycles

Abstract

AbstractMolecular structures of variousd-element M(II) ion chelates with compartmental (N,N)-, (N,O)-, and (N,S)-donor atomic ligands forming as a result of complexing with M(II) three or four articulated metal chelate cycles have been systematized and discussed in detail. It has been shown that, on the whole, such metalmacrocyclic compounds, as a rule, have molecular structures with non-coplanar chelate nodes and non-coplanar macrocycles. The review covers the period 2000–2017.
