摘要
NiF2 was oxidized at similar to 20 degrees C, to NiF62- by sunlight- or ultraviolet light-irradiated F-2 in liquid anhydrous hydrogen fluoride (aHF) containing alkali hydrofluorides {AF(HF)(x)}. Quantitative formation of NiF62- can be achieved with strongly basic solutions (e.g., KF:HF molar ratio similar to 1:4). Li2NiF6, which was previously unknown, is the least aHF soluble of the alkali NiF62- salts, and was prepared in high purity. (C) 1998 Elsevier Science S.A. All rights reserved.
