Coordination compound - Ligands and chelates: Each molecule or ion of a coordination compound includes a number of ligands, and, in any given substance, the ligands may be all alike, or they may be different. kasandbox. In its initial stages, the model was a purely electrostatic one known as crystal field theory which treats the ligand ions as simple point charges that interact with the five atomic d orbitals of the central ion. Coordination drawings definition: “Coordination (sometimes called Composite) is critical to the success of any commercial or institutional building project today. Naming Coordination Compounds Author: Kit Mao Department of Chemistry, Washington University St. The theory is based on the electrostatics of the metal-ligand interaction, and so its results are only approximate in cases where the metal-ligand bond is substantially covalent. In -bonded complexes, which orbitals are non-bonding? Label each of the following, with the type of metal-ligand interaction ( -interaction, -donor or -acceptor) In the -donor and -acceptor cases, which set of metal orbitals in interacting with the ligand orbitals? The chemistry is based on pincer complexes with attention to the uniqueness of the coordination geometry (square-planar or pseudotetrahedral), which is crucial in allowing for particular reactivity toward small molecules.
