metal transition
11Metal amides — are a class of coordination compounds composed of a metal center with amide ligands of the form NR2. Amide ligands have two electron pairs available for bonding. In principle, they can be terminal or bridging. In these two examples, the… …
12Metal aquo complex — Metal aquo complexes are coordination compounds containing metal ions with only water as a ligand. These complexes are the predominant species in aqueous solutions of many metal salts, such as metal nitrates, sulfates, and perchlorates. They have …
13Metal nitrido complex — Metal nitrido complexes are coordination compounds and metal clusters that contain an atom of nitrogen bound only to transition metals. These compounds are molecular, i.e. discrete in contrast to th polymeric, dense nitride materials that are… …
14TRANSITION (MÉTAUX DE) — Les cinquante six éléments chimiques dits de transition actuellement connus comportent tous, soit à l’état d’élément simple, soit dans un état oxydé stable, une sous couche électronique d ou f partiellement remplie. L’existence de niveaux… …
15Metal acetylacetonates — are coordination complexes derived from the acetylacetonate anion and metal ions, usually transition metals. The ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six membered chelate ring.… …
16Metal nitrosyl — Metal nitrosyls are complexes that contain transition metals bonded to nitric oxide, NO. [Hayton, T. W.; Legzdins, P.; Sharp, W. B. Coordination and Organometallic Chemistry of Metal NO Complexes Chemical Reviews 2002, volume 102, pages 935 991;… …
17Transition berezinsky-kosterlitz-thouless — En physique théorique la transition de Berezinky Kosterlitz Thouless est une transition de phase obtenue dans le modèle XY à deux dimensions (ou modèle planaire) en variant la température. Sommaire 1 La transition BKT 2 Autres modèles et… …

19Metal-insulator transition — Metal insulator transitions refer to changes in the transport properties of a given material. Roughly speaking, materials can be classified as metals, allowing for good conductivity of electric charges, and as insulators, where conductivity of… …
20Metal halide complex — Metal halide complexes are coordination compounds containing metal ions with only halides as a ligands. These complexes are common for many metals and some are important technologically. They have the general stoichiometry [MXn]z [1] Contents 1… …
