摘要：

The UV photolysis of krypton-fluorine mixtures at -196-degrees-C readily affords KrF2. Variable-temperature Raman studies on this material indicate a temperature-dependent phase transition at -80-degrees-C. The low-temperature UV photolysis of krypton-fluorine mixtures in the presence of Lewis acids (AsF5 or SbF5) only affords KrF2. Variable-temperature Raman studies on the resulting mixtures show that Kr2F3+SbF6-, alpha- and beta-KrF+ Sb2F11-, KrF+ AsF6- and KrF+ As2F11- are formed on warming the mixtures.
