    Description / Table of Contents: Redetermination of Structure and Properties of the Isotypic Sodium Tetraamido Metallates of Aluminium and GalliumCrystals for x-ray structure determination of NaAl(NH2)4 and NaGa(NH2)4 were obtained by the reaction of the metals with ammonia in autoclaves at 100°C and P(NH3) = 60 bar within 7 days.

    Description / Table of Contents: Cs5[Na{W4N10}]: Das erste Nitridowolframat(VI) mit GerüststrukturCs5[Na{W4N10}] wurde aus einem Gemenge von NaNH2, CsNH2 und Wolframpulver (Molverhältnis 1 : 10 : 4) bei 700°C in Autoklaven dargestellt. Nach beendeter Reaktion ist das Nitrid in einer Alkalimetallmatrix eingebettet. Dunkelrote Kristalle werden durch Auswaschen des Alkalimetalls mit flüssigem Ammoniak bei Raumtemperatur isoliert. Die Struktur von Cs5[Na{W4N10}] wurde über Röntgeneinkristalldaten bestimmt: I41 (Nr. 80), Z = 4, a = 13,926(3) Å, c = 8,723(3) Å, Z(Fo2) ≥ 3σ(Fo2) = 1535, Z(Variable) = 63, R/Rw = 0,040/0,052.An feuchter Luft hydrolysiert die Verbindung schnell zu Oxowolframat und Ammoniak. Sie enthält ein Tetraedergerüst ∞3[WNN3/21.5-]. Natrium ist von vier terminalen Stickstoffliganden umgeben. Einschließlich des Natriums ergibt sich eine Anordnung vom β-Cristobalittyp ∞3[Na{W4N10}5-]. Dieses enthält Caesium in allen Lücken, sogenannten Friauf-Polyedern, die durch zwölf Stickstoffliganden gebildet werden.
    Notes: Cs5[Na{W4N10}] was prepared from a mixture of NaNH2, CsNH2 and tungsten powder (molar ration 1 : 10 : 4) at 700°C in autoclaves. After the reaction is finished the nitride is embedded in an alkali metal matrix. Dark red crystals were isolated by washing out the alkali metal with liquid ammonia at room temperature. The structure of Cs5[Na{W4N10}] was solved by X-ray single crystal data: I41 (No. 80), Z = 4, a = 13.926(3) Å, c = 8.723(3) Å, Z(Fo2) ≥ 3σ(Fo2) = 1535, Z(Variables) = 63, R/Rw = 0.040/0.052.The compound is highly sensitive against moisture giving oxotungstates and ammonia. It contains a framework of tetrahedra ∞3[WNN3/21.5-]. Sodium shares four terminal nitrogen ligands. Including sodium a distorted, β-cristobalite type arrangement ∞3[Na{W4N10}5-] results. It contains caesium in all interstices formed by twelve nitrogen ligands in so-called Friauf polyhedra.
