Synthesis and Structure of an Ammonium Diamidodioxophosphate(V), NH4PO2(NH2)2The ammonolysis of P3N5 under ammonothermal conditions (T = 400°C, p(NH3) = 6 kbar, 14 d in autoclaves) in the presence of small definite amounts of water leads to the formation of NH4PO2(NH2)2. The structure was solved by single crystal X-ray methods.NH4PO2(NH2)2: P21/c (Nr. 14), a = 6.886(1) Å, b = 8.366(2) Å, c = 9.151(2) Å, β = 111.78(3)°, Z = 4, R1/wR2 = 0.026/0.072, Z(Fo2 〉 2σ(Fo2)) = 1183, N(variables) = 87. In NH4PO2(NH2)2 the anions [PO2(NH2)2]- are linked to chains by N—H … N and N—H … O bridge bonds. The ammonium ions are located between these chains and are donors for N—H … O bridge bonds which connect the chains three-dimensionally.
Notes:
Bei Ammonolysen von P3N5 unter ammonothermalen Bedingungen (T = 400°C und p(NH3) = 6 kbar 14 d in Autoklaven) führt eine geringe, definierte Menge Wasser zur Bildung von NH4PO2(NH2)2. Die Struktur wurde röntgenographisch am Einkristall bestimmt.NH4PO2(NH2)2: P21/c (Nr. 14), a = 6,886(1) Å, b = 8,366(2) Å, c = 9,151(2) Å, β = 111,78(3)°, Z = 4, R1/wR2 = 0,026/0,072, Z(Fo2 〉 2σ(Fo2)) = 1183, Z(Variable) = 87. In NH4PO2(NH2)2 sind Anionen [PO2(NH2)2]-, über N—H … N und N—H … O Brückenbindungen zu unendlichen Ketten verknüpft. Die Ammoniumionen liegen zwischen den Ketten und wirken als Donatoren für N—H … O Brückenbindungen, die die Ketten dreidimensional verknüpfen.
