Abstract
Zn2(NH4)2P6O18.8H2O corresponds to a new structural arrangement in the family of the MII2MI2P6O18.nH2O cyclohexaphosphates. This salt is tri clinic, with Z = 1 and the following unit cell : a = 8.717(7), b = 10. 297(8), c = 7.409(7) angstrom alpha = 104.82(2), beta = 111.03(2), gam ma = 70.96(2)degrees Layers built by ZnO6 octahedra and P6O18 ring ani ons spread in planes (011). Between these layers are located the ammon ium groups and one of the water molecules which is not involved in ass ociated cation-coordination polyhedra. The geometry of the three-dimen sional hydrogen-bond network is reported.
