|Section2= |Section3= |Section4= }} Zinc hydride is an inorganic compound with the chemical formula ZnH2. It is a white, odourless solid which slowly decomposes into its elements at room temperature; despite this it is the most stable of the binary first row transition metal hydrides. A variety of coordination compounds containing Zn-H bonds are used as reducing agents, however ZnH2 itself has no common applications. == Discovery and synthesis == Zinc(II) hydride was first synthesised in 1947 by Hermann Schlesinger, via a reaction between dimethylzinc and lithium aluminium hydride; a process which was somewhat hazardous due to the pyrophoric nature of Zn(CH3)2. :Zn(CH3)2 + 2 LiAlH4 → ZnH2 + 2 LiAlH3CH3 Later methods were predominantly salt metathesis reactions between zinc halides and alkali metal hydrides, which are significantly safer.〔Egon Wiberg, Arnold Frederick Holleman (2001) ''Inorganic Chemistry'', Elsevier ISBN 0-12-352651-5〕 Examples include: :ZnBr2 + 2LiH → ZnH2 + 2LiBr :ZnI2 + 2 NaH + → ZnH2 + 2NaI :ZnI2 + 2 LiAlH4 → ZnH2 + AlH3 + 2LiI Small quantities of gaseous zinc(II) hydride have also been produced by laser ablation of zinc under a hydrogen atmosphere and other high energy techniques. These methods have been used to assess its gas phase properties. 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「Zinc hydride」の詳細全文を読む スポンサード リンク
