    Description / Table of Contents: Kristallstruktur des AmmoniumdiamidodiphosphatAmmoniumdiamidodiphosphat, ((NH4)2(P2O4(NH2)2)), kristallisiert monoklin mit der Raumgruppe P21/c und den Gitterkonstanten a = 7,634(4), b = 8,237(4), c = 7,127(4) Å und β = 116,63(4)°. Die Elementarzelle enthält zwei Formeleinheiten. Die Strukturbestimmung mit visuell-geschätzten Daten ergab für 508 beobachtete unabhängige Reflexe einen R-Wert von 0,084. Die zentrosymmetrischen Diamidodiphosphat-Anionen sind durch N—H…O Wasserstoffbrücken von Ammonium-Kationen zu unendlichen Ketten in der [010]-Ebene verknüpft. Benachbarte zweidimensionale Netzwerke dieser Art werden sowohl durch die Ammonium-Kationen als durch direkte N—H…O Wasserstoffbrücken mit einander verbunden. Die folgende Bindungslängen wurden ermittelt: P—P 2,186(4), P—O 1,473(6) und 1,512(5), P—N 1,663(5) Å.
    Notes: Ammonium diaminodiphosphate, (NH4)2(P2O4(NH2)2), monoclinic with the space group P21/c and cell dimensions a = 7.634(4), b = 8.237(4), c = 7.127(4) Å and β = 116.63(4)°. There are two formula units per unit cell. The structural analysis with visually estimated data yielded an R value of 0.084 for 508 unique observed reflections. The centrosymmetric diaminodiphosphate anions are linked through N—H…O hydrogen bonds from the ammonium cations into infinite chains lying in the [010] plane. Adjacent twodimensional networks of this nature are connected to one another through both the cations and through direct N—H…O hydrogen bonds. The following bond lengths were obtained: P—P 2.186(4), P—O 1.473(6) and 1.512(5), P—N 1.663(5) Å.
