Cesiumauride Ammonia (1/1), CsAu⋅NH3: A Crystalline Analogue to Alkali Metals Dissolved in Ammonia?

Abstract

Treating CsAu with liquid NH3 yields the deep blue ammoniate CsAu⋅NH3 (see picture and structure). The unusual electronic structure, as well as the properties, indicate that this unique compound, which behaves like an alkali metal when dissolved in ammonia, may serve as a guide to a more thorough understanding of solvated electrons.
