Cuprate (original) (raw)

About DBpedia

Cuprate loosely refers to a material that can be viewed as containing anionic copper complexes. Examples include tetrachloridocuprate ([CuCl4]2−), the superconductor YBa2Cu3O7, and the organocuprates (e.g., dimethylcuprate [Cu(CH3)2]−). The term cuprates derives from the Latin word for copper, cuprum. The term is mainly used in three contexts: oxide materials, anionic coordination complexes, and anionic organocopper compounds.

(en) Cuprate (von lateinisch cuprum für Kupfer) sind chemische Verbindungen, die ein kupferhaltiges Anion enthalten. Dabei lassen sich mehrere unterschiedliche Arten von Cupraten unterscheiden. (de) Un cuprate est un composé chimique dans lequel du cuivre forme un anion ou un complexe dont la charge globale est négative. Dans le cas du complexe, les ligands sont généralement des cyanures, des hydroxydes ou des halogénures. Bien qu'ils soient des isolants électriques à l'état pur, à l'état « dopé », les cristaux de cuprates comptent parmi les « nouveaux supraconducteurs » (supraconducteurs non conventionnels) et de la classe dite des « supraconducteurs à haute température critique » (HTSC). Ils sont aussi classés parmi les « matériaux à électrons fortement corrélés parmi lesquels ceux qui sont isolants à cause des interactions, comme les cuprates, sont appelés isolants de Mott ».
