Chemical preparation and XRD data for a new triphosphate CuNa_3P_3O and two cyclotriphosphates SrRbP_3O_9-3H_2O and SrRbP_3O_9

摘要

Methods of chemical preparation and XRD data are reported for a new triphosphate CuNa_3P_3O_10 and two cyclotriphosphates SrRbP_3O_9•3H_2O and SrRbP_3O_9. SrRbP_3O_9-3H_2O was prepared by the method of ion-exchange resin, while CuNa_3P_3O_10 and SrRbP_3O_9 were obtained by total dehydration of CuNa_3P_3O_10-12H_2O and SrRbP_3O_9-3H_2O, respectively. CuNa3P3O10 crystallizes in the hexagonal system, with space group P-3,c, Z=2, and the following unit-cell dimensions: a=b = 7.022(1) A, c = 9.217(l) A, M(20) = 81, F(20) = 117(0.003 419,50), and V=393.24(2) A3. SrRbP_3O_9-3H_2O is orthorhombic, with Z=4, space group Pnma, and the following unit-cell dimensions: a=9.120(l) Å, b = 8.141(1) Å, c= 15.234(1) A, M(20) = 5.1, F(20) = 5.8(0.0173,199), and V= 1131.1(3) A3. SrRbP_3O_9 is monoclinic, with space group P2,/m or P2_1, Z=4, and the following unit-cell dimensions: a= 14.958(3) A, b = 8.503(2) A, c=7.898(2) A, β = 122.19(2)°, Af(20) = 9.9, F(20)= 16.5(0.0189,64), and V=850.2(8) Å3.
