Coordination chemistry Coordination chemistry Chelation (from Greek χηλή, chelè, meaning claw) is the process of reversible binding of a ligand, the chelator or chelating agent, to a metal ion, forming a metal complex, the chelate. ...more on Wikipedia about "Chelation"
Linkage isomers are isomers in which a particular ligand bonds to a metal ion (to form coordination compound) by means of different donor atoms. ...more on Wikipedia about "Linkage isomer"
In chemistry, a non-coordinating anion is an anion that only weakly interacts with its cation. Usually the cation is a metal complex, such as [(C5H5)2ZrR]+ where R is an alkyl group. ...more on Wikipedia about "Non-coordinating anion"
Oxidative addition and reductive elimination are two important classes of reactions in organometallic chemistry. Their relationship is shown below where y represents the number of ligands on the metal and n is the oxidation state of the metal. ...more on Wikipedia about "Oxidative addition"
In chemistry, pincer ligands are a specific type of chelating ligand ( chelation). A pincer ligand wraps itself around the metal center to create bonds on opposite sides of the metal as well as one in between. The effects pincer ligand chemistry on the metal core electrons is similar to amines, phosphines, and mixed donor ligands. This creates a unique chemical situation where the activity of the metal can be tailored. For example, since there is such a high demand on the sterics of the complex in order to accommodate a pincer ligand, the reactions that the metal can participate in is limited and selective. ...more on Wikipedia about "Pincer ligands"
A post-metallocene catalyst is a kind of catalyst for olefin polymerization. "Post-metallocene" refers to the generation of catalysts following Kaminsky catalysts, which are metallocene catalysts discovered in 1980 by Walter Kaminsky, and have been predominant in the olefin polymerization catalyst area for the past quarter century. The first post-metallocene catalysts appeared in the late 1990s. ...more on Wikipedia about "Post-metallocene catalyst"
In inorganic chemistry, the trans effect is the labilisation of ligands trans to certain other ligands, which can thus be regarded as trans directing ligands. It is attributed to electronic effects and it is most notable in square planar complexes, although it can also be observed for octahedral complexes. ...more on Wikipedia about "Trans effect" www.shortopedia.com never sleeps.

π backbonding, also called π backdonation, is a concept from chemistry, that refers to the flow of electrons from an atomic orbital on one atom to a π anti-bonding orbital that belongs to other atoms. It is especially common in the coordination of multi-atomic ligands to metal centres, where electrons from the metal flow towards the bond between the ligand atoms, thereby relieving the metal from excess negative charge and allowing it to bond with the ligands. ...more on Wikipedia about "Π backbonding"
