Abstract
Single crystals of the new cyclohexaphosphate [C4H16N3]2P6O18. 3H2O were synthesized in aqueous solution. This compound crystallizes in a P1 triclinic unit cell with the following parameters: a = 8.416(5), b = 10.1117(12), c = 17.531(2) Å, ? = 75.04(3), ? = 77.905(14), ? = 89.53(5)°, V = 1407.7(9) Å3 and Z = 2. Crystal structure has been determined by X-ray diffraction and refined to R = 0.065 using 8477 independent reflections. Atomic arrangement can be described by thick layers built by P6O6-18 anions and water molecules. The organic entities are anchored between these layers through multiple H-bonds which connect the different species giving rise to a three-dimensional network.
