Abstract

The cyclotriphosphate hexahydrate of manganese and silver, MnAg₄ (P₃O₉)₂.6H₂O, was prepared by Boullé's process. MnAg₄(P₃O₉)₂.6H₂O crystallizes in the triclinic system, P-1, Z = 1 and its structure was determined by Rietveld's method. The refinement of 54 parameters by this method, using 1752 independent reflections leads to Rw_p = 0.098, R_p = 0.065 and R_B = 0.033 on the basis of its isotype NiAg₄(P₃O₉)₂.6H₂O. The unit cell parameters of this salt are the following a = 8.824(1)Å, b = 8.485(1)Å, c = 6.609(1)Å, α = 90.30(1)°, β = 92.89(1)° and γ = 107.28(1)°. The thermal behavior of this new compound was studied, between 25 and 600°C, under atmospheric pressure by infrared spectrometry, X-ray diffraction, thermal analyses TGA and DTA coupled. This study allows us the identification and the crystallographic characterization of a new phase, MnAg₂(PO₃)₄ isotype of ZnRb₂(PO₃)₄, obtained between 350 and 450°C, mixed with the long-chain polyphosphate of silver AgPO₃. The kinetic characteristics of the dehydration of MnAg₄(P₃O₉)₂.6H₂O and the thermal phenomena accompanying this dehydration were determined and discussed on the basis of the proposed crystalline structure. The vibrational spectrum of the, MnAg₄(P₃O₉)₂.6H₂O, was examined and interpreted in the domain of the stretching vibrations of the P₃O₉ rings, on the basis of the proposed crystalline structure and in the light of the calculation of the thirty fundamental IR frequencies for the idealized D_3h symmetry.
