翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ate complex ： ウィキペディア英語版 Ate complex An ate complex in chemistry is a salt formed by reaction of a Lewis acid with a base whereby the central atom increases its valence.〔''Advanced organic Chemistry, Reactions, mechanisms and structure'' 3ed. Jerry March ISBN 0-471-85472-7〕 (Note that in this definition the meaning of valence is equivalent to coordination number). Often in chemical nomenclature the phrase ''ate'' is suffixed to the element in question. For example, the ate complex of a boron compound is called a borate. Thus trimethylborane and methyllithium react to form the ate compound Me4B−Li+, lithium tetramethylborate(1-). This concept was introduced by Georg Wittig in 1958 The term is usually reserved for the complexes of metals in groups 2, 11 and 12.〔Encyclopedia of Inorganic Chemistry, 1994, John Wiley and Sons, ISBN 0-471-93620-0〕 Ate complexes are inversely analogous to onium compounds. Lewis acids form -ate ions when the central atom gains one more bond and becomes a negative anion. Lewis bases form onium ions when the central atom gains one more bond and becomes a positive cation.〔''Advanced Organic Chemistry: Reactions and mechanisms'', Maya Shankar Singh, 2007, Dorling Kindersley, ISBN 978-81-317-1107-1〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ate complex」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
