Popis:	Synthesis and complete structural characterization by X-ray diffraction, DTA, GTA and IR are given for a new cyclohexaphosphate: (1,6-NH3C6H12NH3)2 (1-NH3C10H7)2P6O18.2H2O. This compound is monoclinic P21/c with the following unit-cell parameters: a = 11.861(2)A, b = 10.104(1)A, c = 19.664(6)A, β = 96.44(2)°, and Z = 2. The crystal structure has been solved and refined to R = 0.033 using 3928 independent reflections. The atomic arrangement can be described as layer organisation. Layers built by P6O18 ring anions and water molecules spread in the plans (100). Between these layers are located the organic groups which form hydrogen bonds with oxygen atoms of P6O18 rings and water molecules. Geometrical characteristics of hydrogen bonds are described. The reported IR study is supported by a delaited theoretical group analysis applied to P6O18 with D6h ideal local symmetry.
