WebMar 18, 2024 · The bonding and antibonding character of ψ + and ψ − also should be reflected in the energy. If ψ + indeed describes a bonding orbital, then the energy of this state should be less than that of a proton and hydrogen atom that are separated. In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. The nature of metal–ligand bonding … See more The composition of coordination complexes have been known since the early 1800s, such as Prussian blue and copper vitriol. The key breakthrough occurred when Alfred Werner reconciled formulas and See more In general, ligands are viewed as electron donors and the metals as electron acceptors, i.e., respectively, Lewis bases and See more Denticity Denticity (represented by κ) refers to the number of times a ligand bonds to a metal through noncontiguous donor sites. Many ligands are capable of binding metal ions through multiple sites, usually because the ligands have See more Virtually every molecule and every ion can serve as a ligand for (or "coordinate to") metals.
