Exchange of one caesium cation of Cs3P7 for NEt3Me+ or NEt4+ in liquid ammonia gave [NEt3Me][Cs2P7]·NH31 and [NEt4][Cs2P7]·4NH32, respectively. The crystal structure of the compounds have been determined. They show the existence of corrugated ∞2[Cs2P7]– layers stacked along the crystallographic a axis in both compounds. The layers are topologically equivalent in 1 and 2. While the layers are repeated in the same orientation in 1, stacking mode AAA, they have two different orientations in 2, stacking mode ABAB, where B is related to A by a mirror plane. The space between the layers contains ammonia of solvation completing the co-ordination of caesium, and the tetraalkylammonium cations.
