We have shown that the molecular structure of monohydrated ammoniaco-metallic phosphates M''NH₄PO₄H₂O is in agreement with the given formula : these substances are ammonium salts and not phosphates of the type M''HPO₄NH₃H₂O. Moreover, the shift of the IR absorption bands as a function of metallic cations M'' and the determination of symmetries by study of non-degenerate vibrations have allowed us to determine the relative environment of the different elements of these substances.Nous avons montré que la structure moléculaire des phosphates ammoniaco˗métalliques monohydratés M''NH₄PO₄H₂O est bien en accord avec cette dernière formule, c'est-à-dire que ces composés sont des sels d'ammonium et non des phosphates du type M''HPO₄NH₃H₂O. De plus,...
