Abstract
Three new cyclohexaphosphates with general formula M0.5((C6H5CH2)2NH2)5P6O18-H2O (M=Co, Cu, Cd) are reported. They crystallize with monoclinic unit-cells and are isotropic. We have determined their structure from the salt M = Co. This later exhibits the following unit-cell parameters: a = 22.739(5), b = 17.682(3), c = 18.342(3) Å, β = 91.22(1)°, Z = 4 P21/n, V = 7373 Å3, and Dx = 1.373 g cm-3. The atomic arrangement can be described as layers containing P6O18 ring anions and CoO6 octahedra spreading in the (101) planes and intercalated by the dibenzylammonium groups and the water molecules. Synthesis and charac terization by X-ray diffraction, IR absorption, and TA are described.
