In general, ligands are viewed as electron donors and the metals as electron acceptors, i.e., respectively, Lewis bases and Lewis acids. This description has been semi-quantified in many ways, e.g. ECW model. Bonding is often described using the formalisms of molecular orbital theory. Ligands and metal ions can be ordered in many ways; one ranking system focu… WebSome ligands (e.g. N O) can display very complex redox chemistry that defies them being ordered in a simple list. Rather than learning some list off by heart and rote memorising it …

WebCO is a strong σ-donor (or σ-base) and a good π-acceptor (or π -acid). The properties of ligated CO depend profoundly upon the identity of the metal center. More specifically, the electronic properties of the metal center dictate the importance of backbonding in metal carbonyl complexes. Most bluntly, more electron-rich metal centers are ...
WebLigands can be anions, cations, and neutral molecules. Ligands act as Lewis bases (donate electron pairs) and central metal atoms viewed as Lewis acid (electron pair acceptor). The nature of bonding between metal to ligand varies from covalent bond to ionic bond. Occasionally ligands can be cations (NO +, N 2 H5 +) and electron-pair acceptors.
