    Description / Table of Contents: On the Knowledge of the New Ionic Ozonides P(CH3)4O3 and As(CH3)4O3P(CH3)4O3 and As(CH3)4O3 were prepared via ion exchange in liquid ammonia and characterized by X-ray-powder, IR, MS and DTA techniques. P(CH3)4O3 and As(CH3)4O3 are isotypic and have a wurtzite-like arrangement of ions with rotationally disordered O3-. (Powder data: P63mc; P(CH3)4O3: a = 687.8(2), c = 964.6(3) pm; As(CH3)4O3: a = 708.6(1), c = 991.0(3) pm). As(CH3)4O3 shows a displacive phase transition at -135°C. The low temperature phase is orthorhombic (a = 715.8(7), b = 1 209(1), c = 943.3(1) pm).
    Notes: P(CH3)4O3 und As(CH3)4O3 wurden mittels Ionenaustausch in fl. NH3 erstmals dargestellt und mit Röntgenpulvermethoden, IR-Spektroskopie, MS und DTA charakterisiert. P(CH3)4O3 und As(CH3)4O3 sind isotyp und bilden eine Ionenpackung im Wurtzit-Typ mit fehlgeordnetem O3-. (Röntgenpulverdaten: P63mc; P(CH3)4O3: a = 687,8(2), c = 964,6(3) pm; As(CH3)4O3: a = 708,6(1), c = 991,0(3) pm). As(CH3)4O3 zeigt bei - 135°C eine displazive Phasenumwandlung. Die Tieftemperaturphase hat orthorhombische Metrik (a = 715,8(7), b = 1 209(1), c = 943,3(1) pm).

    Notes: The bisquaternary ammonium ozonides Me3N+(CH2)n +NMe3(O3-)2 with n = 3, 4, 6 (1, 2, 3), Me3N+(CH2)3+NMe3(O3-)2 · 3 NH3 (1a), Me3N+(p-Ph)+NMe3(O3-)2 (4) and Me3N+(p-Ph)+NMe3(O3-)2 · NH3 (4a) were obtained in quantitative yields by cation exchange starting from CsO3. The compounds 1a and 3 have been studied by single crystal X-ray analysis. The influence of C-H…O and N-H…O hydrogen bonds on the bond length and the bond angle of the ozonide anion is discussed; earlier results are included. The difference between the two bond lengths within the O3- ion [137.4(3) pm and 129.5(3) pm] in 1a is unexpectedly large. Thermal stabilities determined by DTA/TG methods range from 24-83°C.
