| Résumé: | Chemical preparation, crystallographic characterization and vibrational studies are reported for
two new condensed phosphates associated to nickel-rubidium NiRb4(P3O9)2 and strontium-thallium
SrTl4(P3O9)2. SrTl4(P3O9)2 was prepared by the method of ion-exchange resin and NiRb4(P3O9)2
was
obtained by total thermal dehydration of NiRb4(P3O9)2.6H2O. SrTl4(P3O9)2 is rhombhoedral , Z = 2,
space group P-31c, with the following unit-cell parameters : a = 7,424(1) Å, c = 20,176(2) Å and V =
2807.46(2) (Å
3
). NiRb4(P3O9)2 is triclinic, Z = 2, space group P-1, with the following unit-cell
parameters : a = 8,046(9) Å , b = 9,733(0) Å, c = 4,327(5) Å, α = 98.053°, β = 88.616°, γ = 84.761°
and V = 333,95(2) (Å
3). Vibrational study is also reported for the title compounds. |
