Synthesis and crystal structure of cesium-lithium cyclo-hexaphosphate dihydrate

Cs3Li3P6O182H2O is triclinic, PT, with Z = 1 and the following unit-cell dimensions: a = 7.938 (2), b = 7.674 (2), c = 9.556 (2), α = 113.39 (4), β = 93.83 (4), γ = 83.00 (4). The crystal structure was determined using 4,576 reflections leading to a final R value of 0.022. The atomic arrangement of this new cyclohexa-phosphate exhibits several unusual features of disorder affecting both cations and water molecules.
