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. Monodentate ligands include virtually all anions … See more Especially in the area of organometallic chemistry, ligands are classified as L and X (or combinations of the two). The classification … See more Trans-spanning ligands Trans-spanning ligands are bidentate ligands that can span coordination positions on opposite sides of a coordination complex. Ambidentate ligand Unlike polydentate … See more A ligand exchange (also ligand substitution) is a type of chemical reaction in which a ligand in a compound is replaced by … See more WebIn chemical bonding theory, an antibonding orbital is a type of molecular orbital that weakens the chemical bond between two atoms and helps to raise the energy of the molecule relative to the separated atoms. Such an orbital has one or more nodes in the bonding region between the nuclei.The density of the electrons in the orbital is …
