It has the FeF3 structure where the gallium atoms are 6-coordinate. GaF3 can be prepared by reacting F2 or HF with Ga2O3 or by thermal decomposition of (NH4)3GaF6.〔Anthony John Downs, (1993), ''Chemistry of Aluminium, Gallium, Indium, and Thallium'', Springer, ISBN 978-0-7514-0103-5〕 GaF3 is virtually insoluble in water.〔 Solutions of GaF3 in HF can be evaporated to form the trihydrate, GaF3·3H2O, which on heating gives a hydrated form of GaF2(OH).〔 Gallium(III) fluoride reacts with mineral acids to form hydrofluoric acid. ==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「Gallium(III) fluoride」の詳細全文を読む スポンサード リンク
