Abstract
Six new cyclohexaphosphates with general formula M(2)(II)M(2)(I)P(6)O( 18).8H(2)O (MII:Cu2+, Zn2+ and M(I): Rb+, Tl+, K+, NH4+) have been pre pared. Synthesis and characterization by X-ray diffraction, IR absorpt ion and DTA are given. All these cyclohexaphosphates crystallize with triclinic unit cells and are isotypic. We give as example the paramete rs of Cu2Rb2P6O18.8H(2)O : a = 7.438(3), b = 9.257(3), c = 9.615(3)Ang strom, alpha = 116.02(2), beta = 107.04(2), gamma = 83.34(2)degrees; Z = 1; PT; V = 569 Angstrom(3); D-x = 2.674 g cm(-3).
