Webb25 jan. 2024 · Abstract. Schiff bases are a vast group of compounds characterized by … WebbSchiff bases are macrocyclic or macro-acyclic ligands that typically contain both nitrogen and oxygen donors and are often polydentate in coordinating ability. However, the identity of the donor can be varied between sulfur, phosphorus, nitrogen, and oxygen to change the donor properties, and hence the coordination abilities, of the ligand.
