Sur la base de l'etude structurale de Na 3 AlP 3 O 9 N, deux series isotypes de phosphates azotes, les oxynitrures M I 3 M III P 3 O 9 N( M I = Na, K; M III = Al, Ga, In, Ti, V, Cr, Mn, Fe) et M I 2 M II 2 P 3 O 9 N ( M I = Na; M II = Mg, Mn, Fe, Co), ont ete prepares et caracterises. Plusieurs methodes permettent d'acceder a ces composes par des reactions de type gaz-solide ou solide-solide, dans l'intervalle 600-800#&176;C. Ils cristallisent dans le systeme cubique avec un parametre a compris entre 9,2 et 10 A selon la paire cationique envisagee.
From the results of the crystal structure determination of Na 3 AlP 3 O 9 N two isotypic series of nitridophosphates have been characterized with the general formulations M I 3 M III P 3 O 9 N( M I = Na, K; M III = Al, Ga, In, Ti, V, Cr, Mn, Fe) and M I 2 M II 2 P 3 O 9 N ( M I = Na, M II = Mg, Mn, Fe, Co). The preparation methods involve gas-solid or solid-solid reactions in the 600-800#&176;C temperature range. All the oxynitrides are cubic with a parameter value between 9.2 and 10 A depending on the M I / M III or M I / M II cationic couple.
