Polyphosphides, Liquid Ammonia, Tricesium-undecaphosphide-ammonia(1/3) Cs3P113 NH3 Cs3P113 NH3was obtained from a solution of Cs3P11in liquid ammonia. Its structure consists of P113 -cage anions, which coordinate the cesium cations together with ammonia molecules, resulting in a three-dimensional network. The compound completes a family of structures that are derived from the binary phosphide Cs3P11through the stepwise expanding and dismantling of the three-dimensional network of ions by ammonia molecules of coordination or through the exchange of the cesium cations for voluminous molecular cations.
